what does -10+ -28? Who knows?

Answer 1

Just add the two numbers together and keep the negative sign.
You know that 10 + 28 = 38, so
-10 + -28 = -38

Answer 2

-38

-10 + -28
= 10 +28

-38

Answer 3

-38
-10+-28 is the same as saying -10-28

Answer 4

-10 + -28 = -38

When adding signed numbers (or integers) with like signs, add the values (or the "absolute value") and copy the sign.

Exempli gratia (for example, e.g.)

-10 + -28 = (-10) + (-28) = - (10 + 28) = - (38) = -38

7 + 88 = (+7) + (+88) = + (7 + 88) = + (95) = +95 or simply 95


When adding integers with unlike signs, subtract the # with a smaller absolute value from the # with a larger absolute value and take the sign of the # with the larger absolute value.

E.g.

-37 + 31 = (-37) + (+31) = -(37 - 31) = -(6) = -6

-23 + 123 = (-23) + (+123) = +(123 - 23) = +(100) = +100 or
simply 100

73 + -46 = (+73) + (-46) = +(73 - 46) = +(27) = +27 or 27

Answer 5

Think of it like this

-10 + -28 --> -10 -28 = -38

OR

you can think of it this way
-1 (10+28) --> 38 * -1 --> -38

Answer 6

-10 + -28 --> is the same as --> -10 - 28
-10 - 28 = -38

Answer 7

-10+(-28)= -10-28=-38

Answer 8

that means -10 is the mean result, with an interval of plus or minus 28 around the mean. In other words, the true result lies between -38 and +18.

Answer 9

First we put it as -10+(-28), then it become,
-10-28 it is equal to -38 i.e., -10+-28=-38

Answer 10

easy way

+ = money u have in ur pocket
- = money u owe

-10 + -28 = -38 so u owe 38 buxs

-2-5=-7 get it
