Does Multiplication Always Make Things Bigger?

Challenge the intuition that multiplication always increases value.

The Illusion of Growth

When we multiply two counting numbers greater than 1, like 3 and 5, the product is greater than both numbers being multiplied: $3 \times 5 = 15$ .

Because we learn this early on, it is easy to assume that multiplication always makes things bigger. But does this rule hold when fractions get involved?

Predict the Product Size

Select whether a product is > or < based on scaling rules.

1 / 5

You are predicting the outcome of $0.8 \times 1.25$ . Since $0.8$ is between 0 and 1, and $1.25$ is greater than 1, what can you logically conclude about the product?
