In Math, we learned to use substitution into an equation. To substitute the values of pronumerals into a formula means to replace the pronumerals with their corresponding values. When all but one pronumeral in the formula are replaced with numbers, the value of the remaining pronumeral can be evaluated. Order of operations must be observed at all times while evaluating.
and also we learned about how to use formulae. In formulae, letters are used to represent numbers. For example, the formula A lw = can be used to find the area of a rectangle. Here A is the area, l the length and w the width.
