Which sets are not closed under subtraction

Mathematics
1 answer:
anastassius [24]3 years ago
6 0

If you're referring to the different sets of real numbers, it's the ones that you could try to do subtraction and not get an answer that still in that set.

For example, natural numbers (aka 1, 2, 3, 4, ...) are not, because 7 - 11 = -4 and -4 is not a natural number.

Also, whole numbers (aka 0, 1, 2, 3, 4, ...) has the same issue.

Basically any set of real numbers that doesn't include negative numbers will have this issue.

(72 / 8) - 2 x 3 + 1 equals 4

72 / (8 - 2) x 3 + 1 equals 37

72 / (8 - 2) x (3 + 1) equals 48

How can you use the chart to find the length and width of a figure with an area of 100 square feet?
Hatshy [7]
Well, I don't see a chart but I will try! If your shape was a square then one of your side lengths would be 10. If it was a a rectangle then your base and height would be 10 and 10. If it was a triangle then your base could be 10 and your height would be 20. If it was a parallelogram then your base and height would be 10. It it was a trapezoid then your first base would 8 and the other base would be 12 and your height would be 10. Lastly, if your shape was a circle then your radius would be 10. I am sorry if I did not answer your question but I hope this helps! Have good day!
