How do I keep track of numbers when solving two or more digit problems?
When I tired to solve 23 + 45 this morning, i realized that I had forgotten the sum I calculated for 3+5 after I solved 2+4. Also, when I tried to add 71 + 24 in my head, I got 59. I got the numbers backward somehow! Is there some technique to better my memory just enough to solve basic math? This is embarrassing.
