Mathematical expressions allow us to relate numbers using mathematical symbols to make calculations. some examples are:

  • 2 + 3 = 5
  • 4 - 1 = 3
  • 2 × 2 = 4
  • 4 ÷ 2 = 2
  • 2² + 1 = 5
  • (1 + 2) + (2 × 1) = 5
  • (2 + 3) - 4 = 1
  • (2 + 2)² ÷ 4 = 4
  • (2 ÷ 4)² × 4 = 1
  • (2 + 2)² (4 ÷ 2) - (2 × 4)(5 - 1) + 5 = 5

  • 2 × 2 = 4
  • 4 ÷ 2 = 2
  • 2² + 1 = 5
  • (1 + 2) + (2 × 1) = 5
  • (2 + 3) - 4 = 1
  • (2 + 2)² ÷ 4 = 4
  • (2 ÷ 4)² × 4 = 1
  • (2 + 2)² (4 ÷ 2) - (2 × 4)(5 - 1) + 5 = 5
