Can someone Explain Pythagorean theorem, Exponents, Bedmas, Mean, Median, Mode, Range, Area and Perimeter in simple words

Pythagorean Theorem: C²= a²+b²    

a²+b²=c²

C is the longest line of a right angled triangle and a and b are the other two. If you have "a" and "c", but need to find b. You need to sqaure a and then subtract that from c². Then you have b

An Exponent is any example of ². When a small number is above another number. You multiple the "original" number x amount of time. Ex. 3³ 3*3*3

Bedmas is another way of saying "order of operation". Its the order that you calculate functions. It is calculated in this order:  Brackets, Exponents, Division/Multiplication, Addition/Subtraction.

I attached an example of Mean, Median, Mode, and Range.

Area: Area is the total space that a 2D object covers. And to calculate it we have to multiply the length of two sides that share a corner. For example, if we have a rectangle that the length of one side is equal to 3cm and the second side is equal to 5cm. Then we multiply them together to get the area. 3*5=15

Perimeter: The perimeter is the "outline" of a 2D shape. To calculate the perimeter we have to add all the sides together.
