Baker made 45 cakes. He sold 47 of them and bought 12 new cakes. How many more cakes did baker sell than those he bought?
Baker made 45 cakes. He sold 47 of them and bought 12 new cakes. 

First, we need to figure out how many cakes Baker had in total. To do this, we can add the number of cakes he made to the number of cakes he bought. So we have: 

45 + 12 = 57

This means that, in total, Baker had 57 cakes. 

Next, we need to figure out how many cakes Baker sold. To do this, we can subtract the number of cakes he had in total from the number of cakes he sold. So we have: 

47 - 57 = -10

This means that, in total, Baker sold -10 cakes. 

Finally, we need to figure out how many more cakes Baker sold than those he bought. To do this, we can subtract the number of cakes he bought from the number of cakes he sold. So we have: 

-10 - 12 = -22

This means that, in total, Baker sold -22 more cakes than those he bought.
