4 x 6 - 24/4

4 x 6 = 24; 24/4 = 6

Thus, 24 - 6 = 18

Recall "PEMDAS" Parentheses, Exponents, Multiplication/Division, Addition/Subtraction

"Please Excuse My Dear Aunt Sally" as the mnemonic device.

Hello,

there is a small but nevertheless important difference between:

$\displaystyle \frac{4\cdot 6-24}{4}=\frac{24-24}{4}=\frac{0}{4}=0$

or

$\displaystyle 4\cdot 6-\frac{24}{4}=24-6=18$

Now you have the choice!
