Lauren- Algebra at Open Day at Tamaki College

Terminology

Expressions - Mathematical term for no equal sign

Variable - Mathematical term for letters

Coefficient - Mathematical term for number before the letter

Constant - Mathematical term for the number all by itself

When variables are the same, we call them like terms

When adding like terms keep the variable the same.

2a+5a= 7a

4c+5c= 9c

7p-4p= 3p

ab+2ab= 3ab

“Maths eyes”

If there is no number next to the letter the it always means one

2a+4c+5c+5a=

7a+9c

4b+3g+2b+6g= 15bg :(

Not allowed.

If the letters are not the same then keep them separate.

Algedra must be in alphabetical order.

3f+2g+4f+7g=

7f+9g

2a+3a2+4a=

Correct: 3a2 + 6a

If there is a exponent then it stays separate.

Today at Tamaki College we learnt this in maths class B12. I really enjoyed today and would like to come to this school.

I found out to get the little two then highlight it and push control dot. I recently learnt how to do it. If you want to do any challenges then go to freerice.com It donates rice to kids who haven't eaten for days. There's always something to learnt. That's what Miss Dunn said.
