You must have learned "Order of Operations" or PEMDAS by now,
because that's what this whole question is talking about.
Look at the one in the first box:
32 ÷ 4² + 35 - 20 ÷ 5
You know how to do 4², and you know how to do 20÷5, and you know
how to do 4²+35, and you know how to do 35-20 .
But which one should you do first ? ! ?
pEmdas . . . do exponents. 4² = 16
Now you have 32÷16 + 35 - 20÷5
pemDas . . . do division. 32÷16 = 2
and 20÷5 = 4
Now you have 2 + 35 - 4
pemdAs . . . do addition: 2 + 35 = 37
Now you have 37 - 4
pendaS . . . Do subtraction: 37 - 4 = 33 .
That's the whole ugly thing in the first box. It's 33 .
Do the other two boxes the same way. Then you'll have a single number
for each box. Then just line up the three numbers in the order of their size.
This is all just one big PEMDAS exercise. If you do the operations in the
wrong order in one of the boxes, then you'll get the wrong number in that box.
