Math Problem Statement

1. 4 + (3 × 2) + 2^2 = ? 2. 16 − (4 × 3) + 3^3 = ?

Solution

Let's solve the two problems in the image.

1. 4+(3×2)+224 + (3 \times 2) + 2^2

We apply the order of operations (PEMDAS: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction):

  • First, calculate 3×2=63 \times 2 = 6.
  • Then, calculate 22=42^2 = 4.
  • Now, the expression becomes 4+6+44 + 6 + 4.
  • Finally, add them together: 4+6+4=144 + 6 + 4 = 14.

So, the answer to the first problem is 14\boxed{14}.


2. 16(4×3)+3316 - (4 \times 3) + 3^3

Again, applying the order of operations:

  • First, calculate 4×3=124 \times 3 = 12.
  • Then, calculate 33=273^3 = 27.
  • Now, the expression becomes 1612+2716 - 12 + 27.
  • Perform the subtraction and addition: 1612=416 - 12 = 4, and 4+27=314 + 27 = 31.

So, the answer to the second problem is 31\boxed{31}.

Here are 5 related questions to expand on this topic:

  1. What happens if you change the exponent in the first equation to 232^3 instead of 222^2?
  2. How would the second problem change if you used 4×24 \times 2 instead of 4×34 \times 3?
  3. Can you solve a problem like 5+(2×32)+45 + (2 \times 3^2) + 4?
  4. What is the difference between evaluating exponents and performing multiplication first?
  5. How do the rules of parentheses affect the outcome of complex expressions?

Tip: Always follow the correct order of operations (PEMDAS) to avoid mistakes in calculations.
