Divides exactly into a number- eg. 5 is a factor of 10
1 of 22
Type of number:multiple
in the times table of a number- eg. 20 is a multiple of 10, 25 is a multiple of 5
2 of 22
Type of number:square number
can be written as a number multiplied by itself- eg. 9 is a square number because it can be written as 3x3. The first 7 square numbers are 1,4,9,16,25,36,49.
3 of 22
Type of number:prime number
can only be divided by one and itself: 2,3,5,7,11,13,17... are prime
50%=0.5=1/2...divide by 25%=0.25=1/4...halve then halve again 10%=0.1=1/10...divide by 10 1%=0.01=1/100...divide by 100

Special words:
sum: add the words together product: multiply the numbers difference:biggest take away the smallest estimate:round the numbers first and give an approximate answer

Special words:
solve: work out the value of the letter correlation: the relationship between 2 variables, can be positive,negative or no correlation. draw a line of best fit if correlation is positive/negative.

Special words:
expand: multiply out brackets 2(x+3= 2x+6 factorise: put brackets back in x -3x= x(x-3) tessellate: fit shapes together with no gaps

Averages:
mode/model: the most common values or value median: the middle value when they are in order mean: add up all the values and divide by the number of terms range: highest value take away the lowest value
