Question

Explain how to use the combine place values strategy to find 223-119

Answer 1

Answer: 223 - 119 = 104

Step-by-step explanation:

For subtracting 223-119,we will write this as

H T O

2 2 3

- 1  1 9

Noe start from the right we can't subtract 9 from 3 so combine tens and ones places so that 23-19=04(should remember to place 0 before 4), after that we can simply solve the hundred to get the final answer.

H T O

2 2 3

- 1  1 9

 1  0 4

So 104 is the answer.

Answer 2

So, the subtraction looks like this:

   223
  -119
_______

The reason why combining place values here is necessary is that 3 is less than 9 (so I can't just substract in the one's place without going to negative numbers)

so we combine the ones and tens places and substract the whole: 23-19 is four!
   223
  -119
_______
     04

and then we continue
   223
  -119
_______
    204

and that's the result!
