Math Center Level 1 is a precalculus software that aims to assist students with a variety of mathematical calculations. It includes a 2D graphing calculator, advanced and simple calculators, as well as rational and integer calculators.

The Simple Calculator included in this software offers a combination of use simplicity and calculation power. It can handle simple arithmetic operations and even complex formulas. Moving on to the Advanced Calculator, it is a step higher in complexity as compared to the Simple Calculator. The Advanced Calculator has two editing windows - one for editing x and the other for editing f(x). The x window allows you to enter any number or formula containing numbers while the f(x) window can have formulas containing numbers and x.
The Advanced Calculator also works in scientific mode, where all numbers in internal calculations are treated in scientific formats. However, the presence of two editing windows demands switching between them, which can be done either by clicking the "go to x" and "go to f(x)" buttons or directly clicking inside the window. Moreover, if you forget to enter x or f(x), the software automatically assumes them as x=1 and f(x)=x, respectively.
Apart from these calculators, Math Center Level 1 also includes a Graphing Calculator 2D with two panels. The Left Panel has a Magnifying Square represented by a small square with a gray border on it. It is 16 times smaller than the Left Panel, and the Right Panel displays the content of the Magnifying Square magnified 16 times. The software also offers a zoom-in feature, where you can press the "zoom +" button to zoom twice on both the Left and Right Panels. The maximum zoom limit is 8, which can be achieved by clicking the "zoom +" button three times.
Lastly, clicking the "C" button for the Center on Zoom returns the picture to the starting position with no zoom, and the Magnifying Square appears at the center of the Left Panel. Overall, Math Center Level 1 is an excellent math software for students striving to learn precalculus concepts with ease.
