Simplifying 7(2)+4(7)67(-2) + 4(-7) - 6

To simplify an expression that combines integer multiplication with addition and subtraction, follow the order of operations — perform all multiplications before any additions or subtractions:

  1. Multiply first: Compute each product: 7(2)=147(-2) = -14 (different signs produce a negative) and 4(7)=284(-7) = -28 (different signs produce a negative). The expression becomes 14+(28)6-14 + (-28) - 6.
  2. Add: Combine 14+(28)=42-14 + (-28) = -42 (same signs — add the absolute values and keep the negative sign). The expression becomes 426-42 - 6.
  3. Subtract: Compute 426=48-42 - 6 = -48.

The final result is 48-48. This problem shows that when an expression mixes multiplication with addition and subtraction and contains no grouping symbols, all multiplications must be completed first; then the additions and subtractions are performed from left to right.
