Question

30
×60
———
180
22
×40

Explanation:

Step1: Analyze the multiplication

We have \(30\times60\). When multiplying numbers ending with zeros, we can first multiply the non - zero parts and then add the zeros at the end.
The non - zero parts are \(3\times6 = 18\).

Step2: Add the zeros

Since there are a total of \(2\) zeros (one from \(30\) and one from \(60\)) in the original numbers, we add these two zeros to the result of \(3\times6\).
So \(30\times60=1800\) (it seems there was a mistake in the original calculation which gave \(180\) instead of \(1800\)).

Answer:

The correct result of \(30\times60\) is \(1800\).
