If asked to add 8 and -2, we would start by moving eight units to the right of zero. Then we would move two units left from there because negative numbers make us move to the left side of the number line since our last positive is six units to the right of zero, the answer is 6
with negatives its basically going backwards, for example, (-2)+ 17=15 just go backwards.
Adding two numbers with different signs means subtracting the two absolute integers (without sign) and vice versa.
It is IF the integers have different signs.
The examples show that, to find the of two integers with unlike signs first find the absolute value of each integers.
To add two integers with unlike signs: -- Find the difference between their sizes, ignoring their signs. -- Give the difference the sign of the integer with the larger size.
The value of the quotient of two integers with different signs is the same as if the signs were the same. Because the numbers have different signs, the quotient is negative.
To add two integers with opposite signs . . . -- Ignore the signs, and write the difference between the two numbers. -- Give it the same sign as the larger original number has.
You subtract the smaller from the larger and give the answer the sign of the number with the larger absolute value.
Two integerss add to zero when their absolute values are equal and they have opposite signs.
-- write the difference between the integers without regard to their signs -- give the difference the same sign as the larger of the two integers
- Always, if the two integers are both positive. - Sometimes, if the two integers have different signs. - Never, if the two integers are both negative.
-- If the two integers have the same sign, their quotient is positive. -- If the two integers have different signs, their quotient is negative.
If you mean integers, well if you have two integers of the same sign that you are adding, add and the sign stays the same. If you have different signs, subtract and keep the sign of the one that has more. Regular numbers you just add them.
