BRACKETS
Always do brackets first- If no brackets try 3
1 of 19
Timetables
Times indicate the time of arrival at a certain point
2 of 19
Precise
BE CAREFUL
3 of 19
Percentage
10% you move the decimal place to the left one, double up to work out higher percentage
4 of 19
Half way
use time line, when told the halfway point count how many places one way and then do the same the other way
5 of 19
Equation
when working out n look at what has happened to the equation eg 14n 140 n
6 of 19
Less than greater than
≤ less than or equal to 4 ≤ 5
7 of 19
pentagonal prism
10 vertices corners, 5 rectangular faces, 7 total faces
8 of 19
triangular prism
toblerone, 6 vertices, 3 rectangular faces,5 total faces
9 of 19
hexagonal prism
12 vertices, 6 rectangular faces,8 total faces
10 of 19
octagonal prism
16 vertices, 8 rectangular faces, 10 total faces
11 of 19
probability
make into fraction 2beans out of 20 is 2/20, if it says decimal change to a percentage so o.2 becomes 20%
12 of 19
Volume
lengthx width x height
13 of 19
Surface Area
the area of all faces added together, the face is length x width
14 of 19
total length of edges
all the outer lines that create the shape added together
15 of 19
