Simplify the expression using the order of operations. 3×(3+12÷3)−4

17

Step-by-step explanation:

Hey there !!!

for this question we use the PEDMAS rule which stands for  

Parenthesis, Exponents, Divison, multiplication, Addition, and Subtraction

Step 1: solve the equation in the Parenthesis

3×(3+12÷3)−4

in parenthesis problem = 3+12÷3

divide first 12÷3 = 4

then add 4+4 = 7

Step 2: Do mutipliction

3×7-4

in the PEDMAS rule, it said to do multiplication before Addition

so, 3×7-4

multiplication part = 3×7 = 21

Step 3: Do Subtraction

21-3

now we do subtraction because it is the last step and it is also in the PEDMAS

21-3= 17

3×(3+12÷3)−4 = 17
