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.
Hi elaine,
Yup, that is all correct. Well done!
Thank you
Oops, missed out some equations
such as
500 + 1600,
sorry about that
together with 1100 + 1600, 1100 - 500, and I'm not sure if you also want to include those with negative answers..
explain how 3 group partial sums work
give three numbers that make each statement true.
1.- 12+(?) is greater than 20.
needs help in math. I don't know what this is all about but I would to get her some help. Thanks her mom ( Julene )
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.
Yes, you are on the right track! The +/- family is a method of representing addition and subtraction relationships between numbers. It involves finding pairs of numbers that add up to a certain sum or subtract to equal a certain difference.
For the numbers 500, 1100, and 1600, you correctly started by adding 1100 and 500 to get 1600. This is one pair in the +/- family: 1100 + 500 = 1600.
Next, you added 500 and 1100 to get another sum of 1600, which gives you another pair: 500 + 1100 = 1600.
Finally, you subtracted 1100 from 1600 to get 500, which is the difference between two numbers in the +/- family: 1600 - 1100 = 500.
Similarly, when you subtracted 500 from 1600, you got 1100, which is another difference in the +/- family: 1600 - 500 = 1100.
Therefore, your answers are correct! You successfully found all the pairs of numbers in the +/- family for 500, 1100, and 1600. Well done!
