- 1Multiplying with different letters and numbersMultiply all the numbers and put in all the letters (just like putting different fruits in a blender and getting a new flavour out)
- 2Multiplying with same lettersAdd up how many same letters there are and write it as the power
- 3Multiplying with powersAdd the powers together
- 4Dividing powersSubtract the powers
- 5Adding and subtractingGroup terms that match (letters, letters with same powers or numbers belong together, otherwise keep them separate - they must be exactly the same type)
- 6Solving Algebra (letter and number + and -) 7 + y = 10Move number on to numbers side and reverse the sign
- 7Solving Algebra (letter and number x) 4y = 8Move number on to numbers side and reverse the sign
- 8Solving Algebra (two step problem) 2w - 1 = 13Move number on to numbers side and reverse the sign. Then deal with the remaining problem as before
- 9Expanding (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 - 10factorising (find the common factor) 6y - 9common 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) - 11Substitution (swap letter for a number) if 4c - 2p find total value if c=2 and p=3swap c for 2 --> 4 x 2 = 8
swap p for 3 --> 2 x 3 = 6
8+6 = 14
