C1 (a) One way to compute 11 25 mentally is described in the [3]following solution.

I thought of 11 as 10 + 1. I multiplied 10 by 25 which is 250and then added 25 more for 275.

Give another way to find the exact value of this expression mentally.

(b) Consider Norains thinking: [3]To find 126 38, Ill first subtract 40 from 126 which is 86.

Then I have to compensate by subtracting 2 more.The exact difference is 84.

Is her thinking correct? If so, use basic properties to prove her work.If not, explain the error in her thinking.
