What does 48x21x3 count as first?

Yes, multiplication has a associative and commutative law.

There is no fixed order, it depends on how you calculate, take it apart, count it up, count it backwards, it's almost the same difficulty, I personally prefer to calculate 21 3 first.

Calculate 48 times 21 first, you can do it, and the result is the same.

Let's count it in order, first 48 21 = 1008, then 1008 3 = 3024

Just do the math, 48 times 21 and multiply 3!

You can, count in order, and find.

The same level calculation is not in order, so it is generally calculated in order.

It's easier to calculate 3 21 first, and then use 63 48 to get 3024

It's all multiplication, just start from left to right.

Count from left to right, 48 times 21 first

If there is no easy way, just count next to 48.

You can do that first, and multiplication can be swapped with each other.

That's it. Use your brain.

It can simplify the calculation process.
