Think of 23 as 20 + 3 and the 23 times table turns into two tables you already know: the 20s and the 3s. Learn it here with seven practice activities, tricks, worked examples and printable sheets.
Split 23 into 20 and 3: work out the 20s and the 3s, then add them. Split 23 into 20 and 3. 20 × 7 = 140 and 3 × 7 = 21, so 23 × 7 = 140 + 21 = 161.
Work through the activities from left to right. Each one asks a little more of you, and a tick appears when you finish it. Your progress is saved on this device.
Pick the trick that clicks for you. Each one is a different way to the same answer.
Split 23 into 20 and 3: work out the 20s and the 3s, then add them.
23 × 7 = 140 + 21 = 161
Know the 22 times table? Add one more lot: 23 × 7 is 22 × 7 plus 7.
154 + 7 = 161
Look at the last digit of each answer from 23 × 1 to 23 × 10. The same pattern repeats for the next ten answers, so learn it once.
3, 6, 9, 2, 5, 8, 1, 4, 7, 0
23 × 3 is the same as 3 × 23. If you know the 3 times table, you already know this fact, and the same goes for every table you have learned.
3 × 23 = 23 × 3 = 69
Each answer is 23 more than the one before, so you can always count on from a fact you know.
23, 46, 69, 92, 115
23 × 23 = 529 is a square number: 23 rows of 23 make a perfect square. Square facts are good anchors to work from.
23 × 23 = 529
How each answer is found, step by step.
Split 23 into 20 and 3. 20 × 6 = 120 and 3 × 6 = 18, so 23 × 6 = 120 + 18 = 138.
The order does not matter: 7 × 23 is the same as 23 × 7. Split 23 into 20 and 3. 20 × 7 = 140 and 3 × 7 = 21, so 23 × 7 = 140 + 21 = 161.
Split 23 into 20 and 3. 20 × 12 = 240 and 3 × 12 = 36, so 23 × 12 = 240 + 36 = 276.
Split 23 into 20 and 3. 20 × 17 = 340 and 3 × 17 = 51, so 23 × 17 = 340 + 51 = 391.
Ask how many 23s make 184. You know 23 × 8 = 184, so the answer is 8.
Ask how many 23s make 322. Divide to find it: 322 ÷ 23 = 14.
Spotting that a story needs 23 × something is a skill of its own. Work each one out first, then open the answer.
