13 times 15 is 195 — with the shortcut, the division facts and a drill to make it stick
13 × 15 = 195. That is the short answer, and it is the same answer whichever way round you write the two numbers. Below is where 195 comes from, the shortcut that gets you there without counting, the division facts that travel with it, and the fastest way to move it from "I can work it out" to "I just know it".
13 × 15 = 195. Said out loud in the way most classrooms say it: Thirteen fifteens are one hundred and ninety-five.
Multiplying is repeated addition, so 13 × 15 is thirteen fifteens added together, or equally fifteen thirteens added together. Both routes land on 195.
Written the other way round the answer does not change. 15 × 13 = 195 as well, because multiplication is commutative — the order of the two factors never affects the product. That halves how many facts you actually have to learn: get 13 × 15 and you have 15 × 13 for free.
Fifteen is ten plus half of ten. Ten thirteens are 130, half of that is 65, and 130 + 65 = 195.
Both factors are odd, so the answer has to be odd as well. 195 is odd, which rules out a whole class of slips.
Every multiplication fact comes with a division fact on its back. These four all say the same thing about 13, 15 and 195: 13 × 15 = 195; 15 × 13 = 195; 195 ÷ 13 = 15; 195 ÷ 15 = 13.
Learning them as one family rather than four separate things is the single biggest shortcut in times-table practice. If you can answer "195 divided by 13" as fast as you can answer "13 times 15", the fact is genuinely learned rather than just recognised.
In the 13 times table, 195 is the fifteenth step: 13, 26, 39, 52, 65, 78, 91, 104, 117, 130, 143, 156, 169, 182, 195.
In the 15 times table it is the thirteenth step instead: 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195.
Seeing the same number arrive from two directions is what makes it stick. 195 is a landmark in both rows, so whichever table you are drilling you meet it again.
13 × 14 = 182, 13 × 16 = 208, 12 × 15 = 180, 14 × 15 = 210. Those are the answers people most often give by accident when they are a beat too quick.
The gap between neighbours is worth knowing on its own: each extra thirteen adds 13 to the running total, and each extra fifteen adds 15. So if 13 × 15 = 195 is solid, you can reach 13 × 16 by adding 13 rather than starting again.
Recognising a fact and recalling it under time pressure are different skills. A fact you can work out in four seconds still costs you four seconds every time it appears inside a longer calculation.
Short daily bursts beat long sessions: a 60-second drill every day will fix a table faster than one twenty-minute sitting a week. Mix the fact you are learning in among ones you already know so recall is being tested, not the order of a list.
13 times 15 is 195. In words, thirteen fifteens are one hundred and ninety-five.
15 times 13 is also 195. Swapping the two factors never changes the answer, so 15 × 13 and 13 × 15 both come to 195.
195 ÷ 13 = 15, because 13 × 15 = 195. The matching fact is 195 ÷ 15 = 13.
Fifteen is ten plus half of ten. Ten thirteens are 130, half of that is 65, and 130 + 65 = 195.
Yes. 195 is the fifteenth number in the 13 times table, and the thirteenth number in the 15 times table.
