4 ? 4 ? 4 ? 4 = 7
Can you find a way to express the number 7 using four 4s and basic math operations (addition, subtraction, multiplication, and division)?
ANSWER:
4 + 4 - 4 / 4
There's also 4 - (4 / 4 - 4) if you allow parenthesis.
EXPLANATION:
Just a reminder that as per the order of operations in mathematics, the division operator is resolved before the addition and subtraction operators.
