Hp makes great scientific calculators, and many are familiar options that you may already use before, like the HP 35S Vs HP 11C. These scientific calculators are pretty similar and have all essential features, but they are also quite different based on the menu and operation. Today we will see what else the two can offer and which fits you best.
In this comparison, we will talk about the following:
- What are Scientific Calculators
- What are Hp 35S and Hp 11C
- How is the Design of the Hp 35S and Hp 11C
- How is the Display in Hp 35S and Hp 11C
- How is the Operation Mode in Hp 35S and Hp 11C
- How is the Buttons Layout in Hp 35S and Hp 11C
- Hp 35S Vs Hp 11C
Scientific Calculators
There are many different calculator types; one of the most common is the scientific calculator. This calculator is handy for working with science, engineering, and mathematics problems. The unit has more buttons than a regular calculator and lets you do four basic arithmetic operations. These buttons may look complicated, but each has specific functions, such as solving trigonometry problems, scientific numbers with multiplication by 10 to a specific power, π problems, etc. You can use a scientific calculator to solve trigonometry problems, including sine, cosine, tangent, inverses, and hyperbolic functions.

About Hp 35S and Hp 11C
Scientific calculators are handy for students and professionals. The options vary from different manufacturers, but we can never mention a calculator without mentioning Hp, one of the most popular options in the market. We believe most people have used a Hp or Texas Instruments calculator during their student years. Hp still makes some of the most advanced calculators to date, such as the Hp Prime, which you can check in our TI-Nspire CX II Vs Hp Prime. Hp is also famous for its RPN calculators.
Unfortunately, many of their popular calculators are discontinued, so it is challenging to find the model you may already be familiar with. The Hp 35S and Hp 11C are some of the best scientific calculators from the company. The Hp 35S is relatively new to the 11C, which has been around since the 80s. Both models are non-graphing programmable scientific calculators. The most noticeable difference is the layout because 11C follows the classic design with a landscape shape, while the Hp 35S is more modern with a vertical layout.
Like most classic Hp calculators, the Hp 35S and Hp 11C are RPN calculators or Reverse Polish Notation. The other difference is that the 35S also has a decent algebraic mode if you prefer this approach. Outside of these differences, both calculators are very similar, with four stacks of RPN and essential functions. Depending on how you hold the calculator, we think the C11 can be a better choice if you prefer to type while holding the calculator, like when using a smartphone.
Hp 35S and Hp 11C Design
One of the things that we love about Hp 11C is the shape. The landscape design makes this calculator feel more compact than the 35S. Hp is well-known for its rigid build quality, and Hp Prime is an excellent example of Hp’s performance. These calculators are no different because they are solid and will last for years with proper care. The 35S uses two coin batteries, and you should replace them one by one to preserve the data, while the 11C uses three button batteries.
Hp 35S and Hp 11C Display
Another aspect you can notice even at a glance between Hp 35S and Hp 11C is the display because the 35S has a two line-display, marking the modern design of scientific calculators. Still, the 11C’s display quality is impressive, knowing that this model has been around since the 80s; the sharpness and clarity help users input and read the result. The numbers look different, and while it can be subjective, we prefer the Hp 11C as it looks smooth and more solid. The Hp 35S also doesn’t have anti-reflection, so it can be challenging to read from different angles.
Hp 35S and Hp 11C Operation
As for the operation, these calculators use RPN like many other Hp calculators, even though the 35S also has an excellent algebraic mode. RPN, or Reverse Polish Notation, is not as common as the algebraic. Still, many think it is a better and more practical approach because you don’t need a bracket when calculating more complex numbers. For example, in algebraic mode, you can type 2 + 3 x 4 and press = to get the result. In RPN mode, you can type 2, press enter key, 3, and then +.
The calculator will give you the result for the first calculation, and you can enter 4 and the multiplication key to get the result. Since most people are more familiar with algebraic mode, getting used to RPN may require some time, but it is not impossible.
Hp 35S and Hp 11C Layout
Another difference is layout because the Hp 35S is the more modern option, which translates into additional features such as converters and other functions that take spaces on the layout. If you look closer, this calculator has blue and orange buttons. These buttons have a similar function to the shift key on your computer, but the blue is to access the upper function, and the orange key is to access the bottom functions; many buttons in this 35S have three inputs.
The Hp 11C is more straightforward, but the calculator also has secondary functions, just not as complex as the 35S. Since there is much information printed on the layout, some of the tiny texts are challenging to read. We also suggest keeping the manual for reference because you may need it in the future.
Hp 35S Vs Hp 11C
Hewlett-Packard is one of the most well-known calculator manufacturers. This company is famous for its RPN calculators, including these classic scientific models. The Hp 35S and Hp 11C are similar but different in all essential scientific functions. The 11C Voyager series has been around since the 80s and has a landscape design and single-line display. The 35S is a newer model with a portrait design, a two-line display, and more built-in functionalities, making the operation a bit more complex. The 35S is also an RPN calculator with algebraic mode.

The decision is yours because both calculators are good options. We suggest the Hp 11C if you prefer the simpler model, which still packs plenty of power and functionalities. However, we also recommend the Hp 35S if you want more functionalities, including the versatility to change into algebraic mode. The calculator also has Hp’s build quality, but the display is not the best.
