Understand and calculate indices 3 4 Know the meaning of base and index. Know the value of 43 Know the value of 43 × 52.

A number has two parts: In this case, we have written the number 2 to the power of 3. This is sometimes called, “two cubed.” Two cubed means we do 2×2×2 which is 8. Note that we do not do 2×3.
