Two times 45 equals what?
To make the question easier to calculate, we could multiply 45 by two. We could partition 45 into 40 and five. Then, we can multiply each part by two. 40 multiplied by two is 80. And five multiplied by two is 10. Now, all we need to do is add the two parts together. 80 plus 10 is 90.
Two multiplied by 45 is 90.
