Do you know what are the 7 types of Sec 1 Algebra Questions?
Note:
- BODMAS rule is SUPER important.
- (a+b)2 is not the same as a2 +b2
- You cannot combine these two terms – xy is not the same as x2
Algebra math questions can be scary when you are starting out in Sec 1. Check out the following 7 examples.
- Solve the equation – find out the value of the unknown. There can be more than 1 unknown especially after sec 1.
- Substitute – solve the equation after putting the given values in
- Factorise – find the HCM (highest common factor) and get a bracketed expression
- Expand – opposite of factorise. Multiply out to remove the brackets
- Simplify – may involve factorisation and expansion. Collect together same terms.
- Make x the subject – rewrite the equation to be this format “x =…”
- Word problem – form an equation involving an unknown
