Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right) — remembered by the acronym PEMDAS.

Evaluate: 3 + 6 × (5 + 4) ÷ 3 − 7

The answer is 14. Work inside parentheses first (5+4=9), then multiply (6×9=54), then divide (54÷3=18), then add and subtract left to right (3+18−7=14).

What is the absolute value of −18?

The absolute value of −18 is 18. Absolute value represents the distance a number is from zero on a number line, always yielding a non-negative result.

What is the least common multiple (LCM) of 4 and 6?

The LCM of 4 and 6 is 12. It is the smallest positive integer that is evenly divisible by both 4 and 6.

What is the greatest common factor (GCF) of 36 and 48?
