3 + 4 × 5 - 4(3 + 2)
3 + 20 - 4 × 5 = 3 + 20 - 20 = 3 - 7Indicese.g
6^2 = 6 x 6 = 36 - 8MultiplicationFor numbers with the same base simply add the powers together.
2^2 x 2^3 = 2^(2 +3) = 25. - 9Dividingwhen dividing indices subtract the powers
e.g
4^6 divided by 4^3 = 4^7
6-3=3 - 10Raising?multiply powers
e.g
(4^2)^3=4^6
2x3=6 - 11—
