I always get stuck because I never know where to start, and the signs confuse me.
Here's the problem:
10(8)+(4)20
Here's my first step...
20108+4
104
=14
But, that's not right. I checked in the back of the book for the answer, and the answer is 26. I know I didn't do it right, because I struggled with it too much.
Can someone please lead me, and show me what I did wrong?
20108+4
108+4
2+4
