The sum of -1 and -1 is -2.
The sum of 5 and -2 is three.
First point to make is a minus minus = a plus so your sum becomes an eighth plus a sixth. Next you need to apply a common denominator. In the case of eight and six this would be 24 so the sum is now 3 24ths plus 4 24ths = 7/24 or 0.29166667 as a decimal
It is -1.155 kilograms.

The answer is -7. minus three plus one is minus two, adding a negative is the same as subtraction and so plus negative five means minus 5 so the sum is -2-5=-7 The Sum= -3+1-5 -2-5 -7
The sum of 5 and -2 is three.
"minus zero" is the same as plus zero in that it makes no difference to the sum. So the answer is -3.
It is another way to say approximately. If you say, 345.5 is the sum, plus or minus, you mean that 345.5 is not the exact answer, but close enough for the situation.
In Maths double sign symbols can be tabled as = + = - = - = + NB If no symbol is given in front of a number, then read it as plus(+).
