Calculator With the Math Button

This is a calculator that calculates with math, so you can use it without running through a learning curve. It comes with a "Math button" which, when clicked on, brings up a mathematical formula where you can enter the number and then it will display the answer.

When describing how to use various calculator functions, this guide gives the exact keys that you need to press using the symbols shown on the keys. This is known as a ‘key sequence’. If the key sequence accesses the second function of a key, or a function from a menu, the name of this function will be given in brackets at the appropriate point in the key sequence. Names in brackets are thus not keys that you press but simply describe the function that is accessed using the previous key sequence. For example, to turn off the .

When you take standardized tests, you are sometimes allowed the use of a basic scientific calculator. For example, when you take the SATs, you are allowed - and in fact, are encouraged - to bring a calculator that you are familiar with. According to the SAT guidelines, all scientific calculators are allowable. A scientific calculator is a calculator that will calculate science, engineering, and mathematics problems.

Most pocket calculators do all their calculations in binary-coded decimal (BCD) rather than binary. BCD is common in electronic systems where a numeric value is to be displayed, especially in systems consisting solely of digital logic, and not containing a microprocessor. By employing BCD, the manipulation of numerical data for display can be greatly simplified by treating each digit as a separate single sub-circuit. This matches much more closely the physical reality of display hardware—a designer might choose to use a series of separate identical seven-segment displays to build a metering circuit, for example. If the numeric quantity were stored and manipulated as pure binary, interfacing to such a display would require complex circuitry. Therefore, in cases where the calculations are relatively simple, working throughout with BCD can lead to a simpler overall system than converting to and from binary. (For example, CDs keep t.

Also, you might need to use the inverse trig functions to solve problems. Some calculators have the inverse trig functions as actual buttons if not secondary functions of the trig buttons. Other calculators have a simple inverse [inv] button that you can push. To use the inverse button, you push the [inv] button first, and then you push the trig function that you want the inverse of. So, if you needed the inverse tangent function, you would push your degree value, then [inv], then [TAN]. In some other calculators, you will push [inv], then [TAN], and then your degree value. It's important to get to know your calculator, and this is why testing centers tell you to bring a calculator you are familiar with! (Source: study.com)
