- Bracket
- Order
- Division
- Multiplication
- Addition
- Subtraction
Solve:
<u>Given</u>
2 × 3 + 45 ÷ 2 - 6 + 9
<u>Simplify by division</u>
=2 × 3 + 22.5 - 6 + 9
<u>Simplify by multiplication</u>
=6 + 22.5 - 6 + 9
<u>Simplify by addition</u>
=28.5 + 9 - 6
=37.5 - 6
<u>Simplify by subtraction</u>
=31.5
Hope this helps!! :)
