Problem Solving

44 x 2 = 88

Solution :

First I did 40 plus 40 that equalled 80. Then I did 4 times 2 and that equalled 8. So I added 80 and 8 then that equalled 88. And that’s how I did it.  

Problem Solving

510 + 710 = 1220

So I did 5 hundred plus 7 hundred, that equalled 120. Then I did 10 plus 10 that equalled 20. So I added 120 to 20 that equalled 1220.And that is the Answer.
