ANSWER: 532
To find the sum of a problem, you have to add them all together. 243 + 132 + 157
To simplify this we can split it up, let’s start with the hundreds
200 + 100 + 100 = 400
Now we still have 43 + 32 + 57 left
We can simplify this again and do the 10s!
That’s 40 + 30 + 50
This is 120
Now we have 3 + 2 + 7 left which = 12
Now add up all of them together!
400 + 120 + 12 = 532!
