Question

Make the equation true.
12 + 5 =  – 3

  1. 20    
  2. 17    
  3. 22    
  4. 21    

The correct answer is: 20


    To get the missing number, solve one side of the equation first.
    12 + 5 = 17
    To get the missing number, add 17 and 3.
    17 + 3 = 20
    So, when we subtract 20 - 3 = 17, both the sides’ answers are 17.
