Name: Deanna
Who is asking: Student
Level: Elementary
Question:
what is the answer for 20+5+32-3+98
Hi Deanna,
It might help to think of this problem as moving along the number line. Starting at zero, + means move to the right and - means move to the left.
Start at 0 and move 20 units to the right.
Second move 5 more units to the right (20+5=25) so you are at 25.
Third move 32 more units to the right (25+32=57) so now you are at 57.
Now move 3 units to the left (57-3=54) so you are at 54.
Finally move 98 units to the right (54+98=152) so you are at 152.
Thus 20+5+32-3+98 = 152.
I hope this helps,
Penny

Henry counted the chairs in his dining room. "I count 10 chairs. That means I have enough seats for 9 of my friends. That's great!" said Henry happily.

See how to add two numbers together
This selection will show you how to add two numbers together. It won ’ t just give you the answer though, the way your calculator would. You will actually be shown how to add two numbers together, step-by-step, the "long hand" way.
This selection can be sort of fun too, because it can show you how to add together very, very large numbers that can have up to 30 digits each!
Type in your numbers into the boxes below, then click "Add them!". Try some really large numbers if you like!
