- [0](https://md.mova.elamur.ai/free/en/corpora/school/lessons/113-ages/0/) — Everyone gets one year older each year, so in 5 years a child of 8 will be 8 + 5 = 13, and 3 years ago was 8 - 3 = 5.
- [1](https://md.mova.elamur.ai/free/en/corpora/school/lessons/113-ages/1/) — The difference between two ages never changes: if Ben is 4 years older than Mia now, he is 4 years older in every year.
- [2](https://md.mova.elamur.ai/free/en/corpora/school/lessons/113-ages/2/) — If two ages add up to 20 and one child is 4 years older, take the 4 away and halve: (20 - 4) / 2 = 8 and 8 + 4 = 12.
