Exponents Followup Term 3 Week 1

WALT: Solve number problems by using more than one strategy.
What strategy I learn't was tidy numbers and place value and my first problem was 92-34= and it is 68 and how I got was 50+30=80 and I done 8+4=12 then I add them altogether then it made 92 and that's how I got 68. Then my second problem was 81-24=57. And how I got it was I took the 80 from the 81 and I done took away 20 from the 80 then I took away 1 then it made 59 then I took away 2 then it made 57.
