Question

use the numbers 11,8,9 and 3 exactly once to write an expression with a value of 1

Answer 1

Hey Jennifer happy to help!

So you need to think about PEMDAS here and know that you can use parenthasis to our advantage!

If we subtract 11 and 9 to make 2 and divide 8 by our answer (2), we will get 4. Then we can do 4-3 = 1!

Here's how it would look:

8/(11 - 9) - 3 = 1

Answer 3

Remember your Order of Operations! PEMDAS(LR)

Start by thinking, "The out come is a smaller number. I might have to use division and/or subtraction."

Try to make a ZERO - you can always add that 1 at the end.

Do not be afraid to use integers.

I found a solution. You can too!

TIP: Put each number on its own index card. Rearrange without erasing. Also a dry erase marker on a smooth table is a help!
