Answer
23 < 32
Explanation:
According to the information provided
Tim writes the expression;
16 + (16 - 2) / 2
Kevin writes the expression;
18 + (32 - 4) / 2
Step 1: We need to solve the expressions using PEMDAS
P - parenthesis
E - exponent
M - multiplication
D - division
A - addition
S - subtraction
Tim wrote the expression
16 + (16 - 2) / 2
Solving the expression inside the parenthesis first
16 + (14) / 2
16 + 7
16 + 7 = 23
The value for Tim expression is 23
Kevin wrote the expression
18 + (32 - 4) / 2
18 + (28)/2
18 + 14
18 + 14 = 32
The value of Kevin expression is 32
Hence, Tim expression is less than Kevin expression
Mathematically, we have 23 < 32
