So, I understand that the question is asking us to multiply 5 and 23, using two properties of multiplication.
The two properties that I would want to use are:
1)distributive property: 5 times 23 is the same as 2 times20 plus 5 times 3
2)Associative property- it doesnt matter whether we multiply 5*20 or 20*5 - the result is the same!
So let's count!
5*23=5*20+5*3=100+15=115.
So the result is 115.
