Question

The value of the expression 30 - 3x3

Answer 1

PEMDAS

parenthesis, exponents, multiplication, division, addition, subtraction.

Since we know that multiplication comes first before subtraction in PEMDAS, we do multiplication first. We can also put PARENTHESES around (3*3) because the multiplication comes first.

So:

30-(6)=

21!
