The sum of -4 and 7 is 3.
4 or 5-1
No. It is a sum of four terms which can be simplified to a sum of three terms.
The sum of 5 and -2 is three.
The sum of -1 and -1 is -2.
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
"minus zero" is the same as plus zero in that it makes no difference to the sum. So the answer is -3.
the answer is 9
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(+).
-4 minus 8 plus 5 is equal to -7
