Yes, that's what we mean by "-y" or "negative y" -- it's the additive inverse of y.
-y is defined as the number which, when added to y, gives zero.
y + -y = 0
(Zero, in turn, is defined as the additive identity -- the number which, when added to x, gives x.)
It is used to show the inverse (opposite of a number) in algebra.

The commutative property of addition states that the order of adding numbers does not affect the sum. For example, adding 2.5 + 3.7 gives the same result as 3.7 + 2.5, both equaling 6.2. The associative property of addition indicates that when adding three or more numbers, the grouping of the numbers doesn’t change the sum. For instance, (1.2 + 2.3) + 3.4 equals 3.5 + 3.4, which both sum to 6.9.

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.
(6 + 7) + 8 = 6 + (7 + 8)
The GCF of 24 and 64 is 8. You use the distributive property to show another way to write the sum. 8(3 + 8)

arcsine Some calculators show it as SIN-1.
