OK, now let’s try a basic

multiplication problem.

54 × 78 = ?

54 × 78 = 4,212

Yes, true enough, the solution is 4,212.

But it’s best to show how you

found your solution.

54 × 78 = ?

Showing your work proves

to you and your teacher

that you understand what

you’re learning. And if

you’re having trouble,

your work will show what

part you don’t understand

so that you can get help

and stop making the same

error. You’ll be telling the

whole story!
