6 times 18 is 108 — with the shortcut, the division facts and a drill to make it stick
6 × 18 = 108. That is the short answer, and it is the same answer whichever way round you write the two numbers. Below is where 108 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".
6 × 18 = 108. Said out loud in the way most classrooms say it: Six eighteens are one hundred and eight.
18 + 18 + 18 + 18 + 18 + 18 = 108 — that is six eighteens added together.
Written the other way round the answer does not change. 18 × 6 = 108 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 6 × 18 and you have 18 × 6 for free.
Six is five plus one. Five eighteens are 90, one more eighteen makes 108. There is a check built in too: six times an even number always ends in that number's own last digit, and 108 ends in 8 just like 18.
Because one of the factors is even, the answer has to be even. 108 is, so the parity check passes.
108 is a multiple of nine — its digits add to 9, which is itself a multiple of nine.
Every multiplication fact comes with a division fact on its back. These four all say the same thing about 6, 18 and 108: 6 × 18 = 108; 18 × 6 = 108; 108 ÷ 6 = 18; 108 ÷ 18 = 6.
Learning them as one family rather than four separate things is the single biggest shortcut in times-table practice. If you can answer "108 divided by 6" as fast as you can answer "6 times 18", the fact is genuinely learned rather than just recognised.
In the 6 times table, 108 is the eighteenth step: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96, 102, 108.
In the 18 times table it is the sixth step instead: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216.
Seeing the same number arrive from two directions is what makes it stick. 108 is a landmark in both rows, so whichever table you are drilling you meet it again.
6 × 17 = 102, 6 × 19 = 114, 5 × 18 = 90, 7 × 18 = 126. 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 six adds 6 to the running total, and each extra eighteen adds 18. So if 6 × 18 = 108 is solid, you can reach 6 × 19 by adding 6 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.
6 times 18 is 108. In words, six eighteens are one hundred and eight.
18 times 6 is also 108. Swapping the two factors never changes the answer, so 18 × 6 and 6 × 18 both come to 108.
108 ÷ 6 = 18, because 6 × 18 = 108. The matching fact is 108 ÷ 18 = 6.
Six is five plus one. Five eighteens are 90, one more eighteen makes 108. There is a check built in too: six times an even number always ends in that number's own last digit, and 108 ends in 8 just like 18.
Yes. 108 is the eighteenth number in the 6 times table, and the sixth number in the 18 times table.
