Arithmetic Expression

Consider an arithmetic expression of the form a#b=c. Check whether it is possible to replace # with one of the four signs: +, -, * or / to obtain a correct expression.

Example

• For a = 2, b = 3, and c = 5, the output should be

  arithmetic_expression(a, b, c) = true

  We can replace # with a + to obtain 2 + 3 = 5, so the answer is true.

• For a = 8, b = 2, and c = 4, the output should be

  arithmetic_expression(a, b, c) = true

  We can replace # with a / to obtain 8 / 2 = 4, so the answer is true.

• For a = 8, b = 3, and c = 2, the output should be

  arithmetic_expression(a, b, c) = false

  • 8 + 3 = 11 ≠ 2;
  • 8 - 3 = 5 ≠ 2;
  • 8 * 3 = 24 ≠ 2;
  • 8 / 3 = 2.(6) ≠ 2.

  So the answer is false.

Solution

PYTHON

def arithmetic_expression(a, b, c):
    return (a + b == c) or (a - b == c) or (a * b == c) or (a / b == c)


print(arithmetic_expression(8, 3, 12))
