Equations with one variable may be solved using transposition skills to make the variable the subject of the equation.
Two equations in two variables are said to be simultaneous if both must be considered at the same time.
The general form of a quadratic equation is A X squared plus B X plus C equals zero where A is not equal to one.
The solutions to any quadratic equation can be found by substituting the values a, b, c into the quadratic formula.
One polynomial may be divided by another of lower degree by long division (similar to arithmetic long division).
Indicial (or exponential) equations have the form ax = b. If we can write b as a number with a base a and an index, then we can equate the indices to find x. If two equal numbers are written to the same base then the indices must be equal.
