Follow BEDMAS aka solve Brackets first, then Exponents, Division/ Multiplication, Addition/ Subtraction.
Therefore:
5(9+3)-3x4
= 5(12)-3x4 - Assume multiplication if there is no sign in between numbers and brackets
= 60-12
=48
Order of Operations. Solve what's in the parentheses first, multiply the two parts, then subtract the second product from the first.
9 + 3 = 12.
5(12) - 3(4) = 60 - 12 = 48
Final Answer: 48.
48
5(16)= 80, 3*4=12, 80-12=68
