Answer:

1. 25

2. 24

equations below

Explanation:

Order of operations is: PEMDAS = parentheses, exponents, multiplication, division, addition, subtraction

1. 5 x (20/4)

normally we multiply before we divide, but in this case, the division is in parentheses, so we start there

= 5 x 5

then multiply

= 25

------------------------

2. The lovely land of exponents

6^2 (the only way I can type 6 squared, or 6 to the power of 2, where the 2 is up as a superscript)

6^2 - 2 x 6

PEMDAS has us do the exponents before multiplication or subtraction:

6^2 = 6 x 6 = 36

= 36 - 2 x 6

then multiply:

= 36 - 12

then subtract:

= 24
