Math. Subtraction

WALT:We are learning to solve subtraction problems using various strategies.

Problems	Strategy	Answer.
1)294-167=	I can not subtract 7ones from 4 ones because 7 is greater than 4, so I will borrow one ten from 9 tens and add it to 4 ones and I will have 14 ones, so 14-7=7 Since I borrowed one ten from 9 tens, I am left with 8 tens, so 80-60=20 200-100=100 100+20+7=127	=127
2)384-158=	I can not subtract 8ones from the 4 ones because 8 is bigger than 4, so I will borrow one ten from the 8tens and add it to the four and I will have 14 Since I borrow one from 8tens I am left with 70. 14-8=6 70-50=20 300-100=200 200+20+6=226	=226
