Answer:
30 - 18 + 24 ÷ 4 = 18
Explanation:
The order of operations is
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
Use this word PEMDAS to remember the order of operation
Let us solve the problem
30 18 24 4 = 18
∵ 30 - 18 = 12
∵ 24 ÷ 4 = 6
∵ 12 + 6 = 18
That means put (-) between 30 and 18, (÷) between 24 and 4, then put (+) between 18 and 24
∴ 30 - 18 + 24 ÷ 4
- The first operation is the division
∵ 24 ÷ 4 = 6
∴ 30 - 18 + 6
- Start with 30 - 18 because in addition and subtraction we start
with who come first
∵ 30 - 18 = 12
∴ 12 + 6
- Finally add them
∵ 12 + 6 = 18
∴ 30 - 18 + 24 ÷ 4 = 18
