Tables from 15 to 25: Times & Multiplication Tables

Multiplication Tables From 15 To 25

Every table in the band sits in the grid below. Read down a column for one number's full table, or read across a row to compare all eleven numbers at the same multiplier. The cell where a column meets a row is the product.

How Do You Read These Tables?

Each column is one number's times table read top to bottom. The 17 column runs $17 \times 1 = 17$, $17 \times 2 = 34$, down to $17 \times 10 = 170$. The left number is the group size, the multiplier is how many groups, and the cell is the total for that pairing.

The three tinted columns are your reference points. The 20 table is the 2 table with a zero, the 25 table steps in clean quarter-hundreds, and the 15 table is half of the 30s. Fix a value in one of those, then adjust by the small difference to reach a nearby number, and the whole band opens up.

How To Learn The Tables From 15 To 25 (Patterns, Not Memorizing)

Bhanzu teaches the few patterns that generate a table rather than drilling a hundred separate facts into memory. Once you see that every number from 15 to 25 is built from smaller tables you already hold, you can rebuild any row by reasoning instead of recalling it, and that reasoning is the number sense algebra later depends on.

The band comes down to a few structural ideas:

• Split each number into a ten and a units part. Every number here is $10 + k$ or $20 + k$, so $(20 + k) \times n = 20n + kn$. For $23 \times 6$, that is $(20 \times 6) + (3 \times 6) = 120 + 18 = 138$ — the same distributive move you meet in algebra.

• Double a smaller table you know. Several numbers are exactly double a lower one: $16 = 2 \times 8$, $18 = 2 \times 9$, $22 = 2 \times 11$, $24 = 2 \times 12$. So take the smaller table's value and double it. For $18 \times 7$, use $9 \times 7 = 63$, then double to 126.

• The 20 table is the 2 table with a zero. Since $20 = 2 \times 10$, every 20 product is the matching 2 product with a 0 added: $2 \times 7 = 14$, so $20 \times 7 = 140$.

• The 15 and 25 tables ride on the 5s. Both are multiples of 5, so their products always end in 0 or 5. The 15 times table is half of the 30s, and the 25 table climbs in 25s: 25, 50, 75, 100.

• The prime numbers 17, 19, and 23 have no factor shortcut, so build them by the place-value split or by adding the base to the row above.

Learn these moves and any product in the grid becomes something you can rebuild, not something you have to store.

What Do The Tables Look Like In Words?

Reading a table aloud fixes its rhythm before the digits stick. The 16 table reads "one times 16 is 16, two times 16 is 32, three times 16 is 48," on to "ten times 16 is 160." The 25 table is the easiest to chant, stepping twenty-five, fifty, seventy-five, one hundred. Each individual table page linked below writes out its full spoken form.

Why Should You Learn The Tables From 15 To 25?

This band is the natural stretch beyond the school basics, and it is worth more than the numbers alone suggest. Fluency from 15 to 25 makes long multiplication, area problems, and quick estimation noticeably smoother, because so many everyday quantities cluster right here: two dozen, a quarter of a hundred, the teens. And you are not learning eleven new fact-sets one at a time - you are practising the split-and-double method on numbers big enough to matter, which is the reasoning that pays off later in algebra.

Where Do These Tables Appear?

These tables run through daily counting. A carton holds 24 items, a quarter is 25 of anything, and a rugby side is 15 players. Time leans on them too: 15, 20, and 25 minutes are common slots, so scaling a schedule uses these tables directly. Money follows the same pattern - 20 units of a $23 item cost $23 \times 20 = 460$ - and geometry uses 15-, 18-, and 20-unit lengths for areas. Anyone working with dozens, quarters, or teens is reading off this band.

Solved Examples

Example 1

What is $24 \times 6$?

Double the 12 table: $12 \times 6 = 72$, then double to $144$.

Final answer: $24 \times 6 = 144$.

Example 2 (Wrong path first)

A shelf holds 18 books per row across 7 rows. How many books?

Wrong attempt. The rusher multiplies only the tens, reads $18 \times 7$ as $10 \times 7 = 70$, and stops.

Why it breaks. That drops the 8 in every row, so it undercounts by $8 \times 7 = 56$ books.

Correct. Split it: $(10 \times 7) + (8 \times 7) = 70 + 56 = 126$.

Final answer: 126 books.

Example 3

Find $23 \times 8$ by place value.

Break 23 into $20 + 3$: $(20 \times 8) + (3 \times 8) = 160 + 24 = 184$.

Final answer: $23 \times 8 = 184$.

Example 4

$25 \times {?} = 175$.

Divide to find the missing factor: $175 \div 25 = 7$.

Final answer: $25 \times 7 = 175$.

Example 5

Sam saves $19 each week. How much after 9 weeks?

Treat 19 as $20 - 1$: $(20 \times 9) - (1 \times 9) = 180 - 9 = 171$.

Final answer: $171.

Conclusion

• The tables from 15 to 25 sit in one master grid running from 15 to 250, so any two are easy to compare.

• Even bases (16, 18, 20, 22, 24) are each double a smaller table, so doubling rebuilds them fast.

• The 15 and 25 tables ride on the 5s, ending in 0 or 5, while the primes 17, 19, 23 build by the split.

• The 20 table is simply the 2 table with a zero appended.
