Example 1

easy
Is the equation 3+4=8−13 + 4 = 8 - 1 true? Show why.

Solution

  1. 1
    Evaluate the left side: 3+4=73 + 4 = 7.
  2. 2
    Evaluate the right side: 8−1=78 - 1 = 7.
  3. 3
    Both sides equal 7, so the equation is true: 7=77 = 7.

Answer

True: both sides equal 7\text{True: both sides equal } 7
The equals sign means both sides represent the same value, not that the left side produces the right side. Evaluating each side independently and comparing confirms equality. The equation is a balance, not a one-way computation.
