BEDMAS is an acronym that stands for:
When solving mathematical expressions, always follow this order to get the correct result. Operations inside parentheses are solved first, then exponents (like squares or square roots), followed by division and multiplication (from left to right), and finally, addition and subtraction (from left to right).
For example, in the expression \(8 + 2 \times 5\), you would first do the multiplication:
Answer: \(8 + 10 = 18\)
Here's a more complex example:
Solve \(3 + 6 \times (5 + 4)\). First, you solve the parentheses: \(5 + 4 = 9\), then multiply: \(6 \times 9 = 54\), and finally add: \(3 + 54 = 57\).
1. Solve: \(3 + 6 \times (5 + 4)\)
2. Solve: \(8 \times 2^2 - 3\)
3. Solve: \(5 + (2 + 3) \times 4\)
