My strategy
|
1. Tim got some songs on his phone. He downloaded another 128 songs and he now has 162 songs in total. How many songs were on his phone when he first got it?
|
100-100=0
60-20=40
8-2=6
40-6=34
| |
2. There are 22 boxes. Each box holds 9 bottles of juice. How many bottles are there altogether
|
9x20=180
9x2=18
180+18=198
