| Question | Answer |
| Multiplying with different letters and numbers | Multiply all the numbers and put in all the letters (just like putting different fruits in a blender and getting a new flavour out) |
| Multiplying with same letters | Add up how many same letters there are and write it as the power |
| Multiplying with powers | Add the powers together |
| Dividing powers | Subtract the powers |
| Adding and subtracting | Group terms that match (letters, letters with same powers or numbers belong together, otherwise keep them separate - they must be exactly the same type) |
| Solving Algebra (letter and number + and -) 7 + y = 10 | Move number on to numbers side and reverse the sign |
| Solving Algebra (letter and number x) 4y = 8 | Move number on to numbers side and reverse the sign |
| Solving Algebra (two step problem) 2w - 1 = 13 | Move number on to numbers side and reverse the sign. Then deal with the remaining problem as before |
| Expanding (get it out of the brackets) 5(2y - 4) | multiply each part inside the brackets by what is on the outside. 5 x 2y = 10y 5 x 4 = 20 answer = 10y + 20 |
| factorising (find the common factor) 6y - 9 | common factor of 6y and -9 = 3 put this at the front of the brackets 3( ) work out what to do to find each part of the expression 3 x ? = 6y (answer = 2y) 3 x ? = -9 (answer = -3) so final answer = 3(2y - 3) |
| Substitution (swap letter for a number) if 4c - 2p find total value if c=2 and p=3 | swap c for 2 --> 4 x 2 = 8 swap p for 3 --> 2 x 3 = 6 8+6 = 14 |
