In maths class today we were learning about algebra with Mrs. Dunn. We learnt that:- Algebra is numbers and letters
- Variables are the same, we call them like terms (example: 2a,3a)
- Coefficients are numbers just before letter and are joined together
- Constants are numbers by themselves
- Letters must be in alphabetical order
- Equations have equals and expressions have none
Below are some expression question that Mrs. Dunn gave our class and I’ve answered:
2a+5a, 7a
4c+5c, 9a
7p - 4p, 3p
ab + 2ab, 3ab
2a + 4c + 5c + 5a, 7a + 9c
3g + 8h + 6g + 2h, 9g + 10h
3f + 2g + 4f + 7g, 7f + 9g
2a + 3a2 + 4a, 3a2 + 3a
I can see you had "Fun with Mrs Dunn" and learnt a whole lot about Algebra. Well done.
