Arithmetic

8 questions ยท EasyMediumHard

Fast, accurate addition, subtraction, multiplication and division are the base of every aptitude section. Most mistakes here come from rushing a carry or a borrow, not from not knowing the method.

๐Ÿ’ก Quick tricks

  1. Add left to right for a quick estimate, then fix the last digit: 78 + 65 is about 140, and 8 + 5 ends in 3, so the answer is 143.
  2. Check a subtraction by adding the answer back: if 5,104 โˆ’ 389 = 4,715, then 4,715 + 389 must give 5,104.
  3. For division, estimate first (720 รท 9 is close to 80) so a wrong answer stands out.
