You can solve this a couple different ways:
1. You can estimate that 823 is close to 800 and 680 is close to 700. Multiplying these gives you: 800 x 700 = 560,000
2. You can estimate that 823 is close to 825 and 680 is close to 675. Multiplying these gives you: 825 x 675 = 556,875
Remember that estimating does not mean you are supposed to get the actual answer (which in this case is 559,640)--you are just trying to be close. The first estimate above could be done in your head (if you remember that 8 x 7 is 56 and then just add the zeros).
