- These are basic to intermediate multiplication problems.
- Some involve multiplying by multiples of 10 (e.g., 10 × 10 = 100), which is easy using place value.
- Others use standard multiplication facts or require carrying in long multiplication.
- Problems like `8 × 95` can be solved as:
`8 × (100 - 5) = 800 - 40 = 760`
- Problems with numbers close to 100 (like 9 × 101) can be thought of as:
`9 × (100 + 1) = 900 + 9 = 909`
This exercise helps build fluency in multiplication, mental math, and number sense.
