A
A letter or symbol that represents a number
3
Q
Multiplication
A
m x m x m = __^__ ( m^3 )
m x 2 = 2m
Twice of __ = __ x __ = 2__
4
Q
t x t x t x t =
6 x y =
Twice of q =
A
= 4^t
= 6y
= 2q
5
Q
Addition
A
4m + m = ( no. ) ( L ) | 5m
6
Q
s + s + s =
A
= 3s
7
Q

A
t^4 = t x t x t x t
4t = 4 x t
8
Q
Negative + / - positive
A
[ + ] + [ + ] = +
[ — ] + [ — ] = —
9
Q
Negative x / divide positive
A
[ + ] x [ + ] = +
[ — ] x [ — ] = +
[ + ] x [ — ] = —
[ — ] x [ + ] = —
10
Q
Simplify
A
Add / subtract
10a ( 3 + 9a ) = 19a + 3
11
Q
Expand
A
Remove bracket
3( 5t + 4 ) = 15t + 20
