"Perform the operations inside a parenthesis first
Then exponents
Then multiplication and division, from left to right
Then addition and subtraction, from left to right
You can also create a little phrase to memorize, as the sequence:
Please Excuse My Dear Aunt Sally"
48÷2(9+3) = x
Perform the operations inside a parenthesis first
48÷2(12) = x
Then multiplication and division, from left to right
24(12) = x
288 = x
If you rewrite to remove the ambiguity/convention that 'some' believe multiply before divide, by converting division to multiplying by the inverse:
48*(1/2)*(9+3) = x
Perform the operations inside a parenthesis first
48*(.5)*(12) = x
Then multiplication and division, from left to right
24*(12) = x
288 = x
You still get 288
