- [0](https://md.mova.elamur.ai/free/en/corpora/school/lessons/78-two-steps/0/) — Some stories have two changes: first some things come, then some go away, or the other way round.
- [1](https://md.mova.elamur.ai/free/en/corpora/school/lessons/78-two-steps/1/) — Do one step at a time, in the order of the story: 12 stickers, get 5 more, give away 7: 12 + 5 = 17, then 17 - 7 = 10.
- [2](https://md.mova.elamur.ai/free/en/corpora/school/lessons/78-two-steps/2/) — Adding and then taking away gives the same as taking away and then adding, so 12 - 7 + 5 = 10 too.
