- Equations of a straight line
- Simultaneous equations
- Inequalities
- Indices
- Indices show us how many times a
number should be used to multiply itself
E.g. 4² = 4x4 where the ² is and indices. This
is the same in algebra where y² = yxy.
- When multiplying indices
add them together -
Y²xY¹= (2+1) =Y³
- When dividing indices
subtract them -
Y³/Y²= (3-2) =Y¹
- When raising to a
power multiply them
together (Y²)¹= (2x1) =Y²
- When multiplying indices
add them together -
Y²xY¹= (2+1) =Y³
- Indices show us how many times a
number should be used to multiply itself
E.g. 4² = 4x4 where the ² is and indices. This
