A Math Calculator

Did you ever wonder what a calculator does? I know I often did not understand why my teacher would send me out of the classroom to use it. It's not because she didn't want us to figure out for ourselves why a number multiplied times itself wasn't equal to the number you started with. It's because, until I got that calculator, I had no idea what one was. All these years, I took them for granted.

Maple Calculator is a powerful math solver and versatile math learning tool that gives you answers, 2-D and 3-D graphs, and even step-by-step solutions! Whether you are doing simple calculations or working on university-level math problems, Maple Calculator can do it all. Use Maple Calculator to solve algebra problems, calculate the derivative or integral of a function, perform matrix manipulations, explore 2-D and 3-D graphs, and so much more!

This versatile app makes it incredibly easy to enter, solve, and visualize mathematical problems from algebra, precalculus, calculus, linear algebra, and differential equations, for free! You can even enter problems using your camera, so you can check your homework with a click of a button. This app is your essential companion to help you learn math, whether you are in a classroom or learning from home. (Source: www.maplesoft.com)

There are many brands of scientific calculators out there. Each brand operates a little differently. You will need to become familiar with the way your scientific calculator works. For example, when performing trigonometric calculations, some calculators need you to enter the degrees first before choosing the appropriate trig function. Other calculators need you to enter the trig function followed by the degrees. So, for the trig function sin (60), you could be entering either [6] [0] [sin] or [sin] [6] [0]. Also, if you are working with angles, make sure your scientific calculator is using the appropriate angle measurement - either degrees or radians. You will see a button for [DEG] or [RAD]. In some calculators, one or the other will be the secondary function of a button.

Unlike your basic calculator, your scientific calculator will actually follow the order of operations. This means that if you enter 4.32 + 10 x pi, your scientific calculator will perform the multiplication first and then the addition. This helps you out as you can enter a mathematical expression that includes several numbers and several operations. Scientific calculators also have parentheses that you can use to force an operation before another. You use the parentheses the same way you use them in math problems. Remember, your parentheses tell you and your calculator to perform the operations inside first before performing any other calculations. (Source: study.com)
