🔍 How to Solve These:

- Break the 2-digit number into tens and ones.
- Multiply each part by the 1-digit number.
- Add the two results together.

For example:
$ 49 \times 4 = (40 + 9) \times 4 = (40 \times 4) + (9 \times 4) = 160 + 36 = 196 $

This method helps avoid mistakes and builds understanding of place value.
