Problem Solving

We are learning to solve maths problems.

My teacher has 20 stickers.if she uses 12, how many stickers does she have left?


  1. hi lyi sorn it I think the answer is 11 because I know that 20-12 = is 11.from your classmate Glennes

  2. hi it kei I think the answer is 5 because I known that 8-3=5 from your classmate kei.

  3. Hi Lyi Sorn,

    What a great maths problem about stickers!
    The answer is 8. If I had 20 and took away 12 (because) I used them, that leaves 8 left.

    20 - 12 = 8
