Write the +/- family for:500, 1100, 1600.

What do i do?

1100+500=1600

500+1100=1600

1600-1100=500

1600-500=1100

Is that correct? Please help.Thank you.

together with 1100 + 1600, 1100 - 500, and I'm not sure if you also want to include those with negative answers..

Explain your thinking. Use the digits 1, 3, 4, 5, 7, and 9 to write two money amounts that you can subtract by trading 1 dollar for 10 dimes. Then solve.
