The identity property of multiplication states that any number a multiplied by 1, is equal to a: This property almost halves the number of multiplication facts we need to memorize. Since the order doesn't matter, we only really need to memorize numbers below or above (and including) the diagonal shown in green on the chart. This is true for anything being multiplied. We can confirm this by looking at the multiplication chart and seeing that regardless of whether we look at the multiplication fact 2 × 8 = 16 or 8 × 2 = 16, the solution is still 16.

The commutative property of multiplication states that the order of multiplication doesn't matter. Memorizing the multiplication chartĪlthough 100 facts may seem like a large number to memorize when just starting to learn multiplication, the number of facts that need to be memorized can be reduced by using certain properties of multiplication. In other words, to use the multiplication chart, choose the two values that you want to multiply from the grey row and column, then determine what value an imaginary horizontal and vertical line (drawn from the grey column and row respectively) would intersect at to determine the product of the two values. 20 is the product of 4 and 5 and 5 and 4, etc. For example, 25 is the product of 5 and 5. The value in the green diagonal is the product of the column and row values that align with it in grey. Use the green diagonal to understand how the multiplication chart is read.

The green diagonal on the chart represents the squares of the numbers, namely 1 × 1 = 1, 2 × 2 = 4, 3 × 3 = 9, etc. Rows are read horizontally from left to right while columns are read vertically from top to bottom. To use a multiplication chart, first look at the rows and columns in grey in the figure above. Being familiar with all the multiplication facts enables a person to focus on more complex mathematical concepts that involve multiplication, without having to worry about the actual multiplication. It can be helpful for learning and memorizing multiplication facts, which is essential, since multiplication is used throughout all areas of mathematics in some form or another. Home / primary math / multiplication / multiplication chart Multiplication chartĪ multiplication chart, also known as a multiplication table, or a times table, is a table that can be used as a reference for the 100 multiplication facts.
