Explain the steps you can use to find 7 time 2 time 50 mentally

2 times 50 equals 100. 100 times 7 equals 700. Hope that helps!

In your head you take seven and multiply it to itself twice, so you take seven twice which gives you 14. You then take 14 and multiple it to itself 50 times giving you 700.
