Two times as many or as much. Double.
In math, “twice” means “two times as much” or multiplied by 2. It’s the same as doubling a number or a quantity.
Let’s see it in action:
-
Twice 4 is 8, because 2 × 4 = 8
-
If a friend has 3 cookies and we have twice as many, we have 6 cookies
-
If one pencil costs $1, then two pencils cost $2 — that’s twice the price
The word “twice” helps describe real-world situations involving doubling or multiplication by 2. You’ll often see it in math word problems, patterns, and comparisons.
