First, find 4^3. 4x4=16 16x4=64. Then do 64-6=58. Now your problem is 7 x 58 divided by 2. Do left to right and multiplication first. So 7 x 58= 406 and then divide by 2 which would be 203. This my be confusing so here are the steps.
1. Find 4^3
2. 4^3 is 4x4x4=64
3. 64-6=58
4. 58x7=406
5. 406 divided by 2 is 203
6. 203 is your answer
