How to fill out Integers: Addition and Subtraction

1. Understand the concept of integers, which are whole numbers that can be either positive or negative.
2. To add integers, identify the signs of the numbers involved:
3. - If both are positive, add their absolute values.
4. - If both are negative, add their absolute values and keep the negative sign.
5. - If one is positive and one is negative, subtract the smaller absolute value from the larger absolute value and take the sign of the number with the larger absolute value.
6. To subtract integers, change the subtraction to addition of the opposite:
7. - Rewrite the expression 'a - b' as 'a + (-b)'.
8. - Then apply the same rules for adding integers.

How to add and subtract integers without a number line?

In case of integer addition, when one of the two integers is negative and the other one is positive in such cases we subtract the numbers and give the sign of the greater number to the result. When the integers carry the same sign, be it positive or negative, we add the integers and give the common sign to the result.

What is integer addition and subtraction?

Addition and subtraction of integers are two operations that we perform on integers to increase or decrease their values. Integers include whole numbers and negative numbers like 4, 5, 0, -9, -18, and so on. Every number shown on a number line that does not have a fractional part is an integer.

What are the rules for adding and subtracting integers?

SAME SIGN- Add and Keep the Sign! Add the absolute value of the numbers and keep the same sign. DIFFERENT SIGNS- Subtract and Keep the Sign of the Bigger Number! Subtract the absolute value of the numbers and keep the sign of the bigger number.

What are the rules for adding and subtracting numbers?

The Rules: RuleExample +(+) Two like signs become a positive sign 3+(+2) = 3 + 2 = 5 −(−) 6−(−3) = 6 + 3 = 9 +(−) Two unlike signs become a negative sign 7+(−2) = 7 − 2 = 5 −(+) 8−(+2) = 8 − 2 = 62 more rows

What are the rules for adding and subtracting real numbers?

If the signs match, we will add the numbers together and keep the sign. If the signs don't match (one positive and one negative number) we will subtract the numbers (as if they were all positive) and then use the sign from the larger number. This means if the larger number is positive, the answer is positive.
