1 20 times table

Tables 13 to 20

This picks up exactly where the 12 × 12 grid stops. Find your table down the left, then run across to the multiplier you want.

Reading the grid

Pick a number in the top row and a number down the side, then follow both until they meet. Order never changes the answer, so 6 × 13 and 13 × 6 land on the same 78. That halves what there is to learn: once you know one direction, you know the other.

The teens, without memorising them

Every table from 11 to 19 splits into a ten and some units. For 17 × 6, take 10 × 6 = 60 and 7 × 6 = 42, then add: 102. The 20 table is easier still, because 20 × 7 is 7 doubled with a zero on the end, giving 140.

Checking an answer

• Anything multiplied by 5 ends in 0 or 5, and anything multiplied by 20 ends in 0.
• Multiply by an even number and the answer is always even.
• Along any row, each answer is one table-number bigger than the one before it.

If you only need the core set, the 1 to 12 times tables are the ones worth knowing cold. To go further out, the multiplication chart 1-30 extends the same layout, and the multiplication charts hub has the printable and blank versions.
