It is used to show the inverse (opposite of a number) in algebra.

17+42=59
arcsine Some calculators show it as SIN-1.
Assuming that there is a "plus" after the second 58, the answer is - the associative property of addition.
It is used to show the inverse (opposite of a number) in algebra.
Commutatitivity of addition in the fact that you can change the order of 11s and 3t. But also associativity of addition in that you can write the sum of three terms without the need for brackets to show which addition needs to be performed first.

Originally meant "surplus" and was marked on packed goods to show that the weight was over the norm.
A plus sign in an equation is used to indicate addition. It shows that elements or terms are being combined to find the sum.
The GCF of 24 and 64 is 8. You use the distributive property to show another way to write the sum. 8(3 + 8)
(6 + 7) + 8 = 6 + (7 + 8)
