![]() ![]() If the signs are different, multiply or divide, the answer is always negative.Įxample: -25 ÷ 5 = -5 Thus, we have learned to add, subtract, multiply and divide positive and negative numbers. If the signs are the same, multiply or divide and the answer is always positive. Let us learn more about adding and subtracting integers. Every number shown on a number line that does not have a fractional part is an integer. = (-7) + (-2) = -7 - 2 = -9 Multiplying and Dividing Integers Rule: Integers include whole numbers and negative numbers like 4, 5, 0, -9, -18, and so on. (-) - (+) = Change the sign of the number to be subtracted and add them up. ![]() (+) - (-) = Change the sign of the number to be subtracted and add them up.(-) - (-) = Change the sign of the number to be subtracted and add them up.The result takes the sign of the greater number.(+) - (+) = Change the sign of the number to be subtracted and add them up.The result takes the sign of the greater number When subtracting a positive number from a negative number, use the same rule as for adding two negative numbers: add the absolute values and give the.To subtract a number from another number, the sign of the number (which is to be subtracted) should be changed and then this number with the changed sign, should be added to the first number. (‐) + (+) = subtract the numbers and take the sign of the bigger numberĮxample: (-9) + 6 = -3 Subtracting Integers Rule: Examples Same signs give a positive: 3 + ( + 2 ) 3 + 2 5 Same signs give a positive: 3 ( 2 ) 3 + 2 5 Different signs give a negative: 3 + (.(+) + (‐) = subtract the numbers and take the sign of the bigger number.If the signs are different, subtract the numbers and use the sign of the larger number (‐) + (‐) = add the numbers and the answer is negative.Start at 4, and move 7 units to the right. ![]() Subtracting a negative number is like adding a positive you move to the right on the number line.
