Maths Wiz

Picture No.1

Today I have went been Maths Wiz.I had to work a subtraction problem using a type of strategy which makes it easier to answer the equation.On the first picture I had to solve 447 - 356.When you click the wand it takes ten away from the 400 and place to the seven which makes 17 and the 400,300.After that,I did 7 - 6 = 1,4 - 5 = 1 and 4-3= 1.I put the answer together and it makes 113.So the answer is 113.
