### BIDMAS

BIDMAS stands for: Bracets Indices Division Multiplication Addittion Subtraction It is the order in which you do parts of sums in maths.

### What is algebra?

Algebra is using letters to represent unkown values!

### Subsitution

Subsitution is where you know the value of the letters but not the answer! So 7+y=, when y is 5, the answer is 12! Try these: 1) 6+a= a=8 2) 3+u= u=19 3)9-(a+2)= a=4

### Working out the terms

Working out the terms is where you are given all of the numbers but not the terms (the letters.) So 1+y=2, when y is algebra, y=1. Try these: 1) 4+a=29 2) 8+u=7 3) 5=9-(a+2)

### Expanding brackets

Expanding brackets is what you dou if you are given a set of brackets like so: (y+4)(y+8). Even though there is know times symbol, it means times them together because mathemations are lazy and miss the 'x'. What you do is times it all together. So yxy=y^2, yx8=8y, 4xy=4y, 4x8=32. Added all together is y^2+12y+32! By the way you add 4y and 8y together!

### Sticky note

Dividing by a ratio. Firstly, you add the ratio together: eg. 2:7 = 9 and then divide the number you are asked to divide by this total: eg. 36 divided by 2:7 so 2 +7=9 36 divide 9=4.Next you times the total number by each side of the ratio eg. 2:7----->8(2x4):28(7x4).
