Adam has $450. He spends $210 on food. Later he divides all the money into four parts and gives three parts to his mom and one part he keeps for himself. Then he found $20 in one of his Minecraft books being used as a bookmark. Write an expression that shows all of this determine how much money he has left?

Answer 1

Just write the expression in the order you learn the facts:

Adam has $450: 450
He spends $210: 450-210
he divides all the money into four parts and one part he keeps: (450-210)/4
Here you need the parentheses, because 450-210/4 means that only the 210 is divided into 4 parts.
he found $20: (450-210)/4+20

(450-210)/4 + 20

Now, to evaluate that, you do need to know the order of operation. Oddly enough, you do them in the same order you wrote them down...

Answer 3

Answer 4

1000

Answer 5

Answer 6
