To solve this
write out all the numbers that multiply to get to 24 and subtract and see which will be 5
1 * 24 <--- -23
2* 12 <--- -10
3*8 <--- -5
4*6 <--- -2
6*4 <--- 2
8*3<--- 5
12*2<--- 10
24*1<---23
We can see that 8 and 3 multiply to get 24 and subtract to get 5
8*3 = 24
8 - 3 = 5
Hope this helps :)
