How do you add two integers with the same sign?
Add their magnitudes, and keep the same sign for the sum.
How do we add integers with opposite sign?
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.
How do you add two entegers if they have different signs?
Step 1. Ignore the signs, and subtract the smaller unsigned number from the larger one. If the answer is 0, you're done. Otherwise, do step 2. Step 2. Apply to the answer the sign of the given number with the larger magnitude. For example, 5 + (-2) is 3; 12 + (-23) is -11.
When you add two rational numbers how can you determine if your answer will be positive or negative?
The sum of any two numbers has the same sign as the number with the greater absolute value.
How do you add and subtract negative decimals?
The same way you'd add any other negative numbers. Adding a negative is the same as subtracting, and subtracting a negative is the same as adding. (-2) + (-2) = (-4) (-2) - (-2) = 0 you are wrong if you add or subtract two negitives its always a positive dont you know your math. And the second problem you have is wrong to because when you subtract two negitives you change the sign of the secong number to positive and you change the subtraction sign to a addition sign.
