![]() 3 – (-2) = (-2) will be 2, then proceed to addition. When subtracting two negative numbers, the general rule must follow. Let’s have an example: 5 – 3 = 5 and 3 are a positive number.ĥ – 3 = Change the sign of the subtrahend, 3 change to -3 then addī. Subtracting both a positive number can be computed in the usual way. A negative subtrahend changes to the positive sign and a positive subtrahend will be negative.Ī. The general rule for a positive or a negative number is to change the sign of a subtrahend and proceed to addition. Subtraction of a Positive or Negative Numbers Take the larger number (9) and subtract the smaller number (3) and copy the larger number’s sign (+). Take the larger number (6) and subtract the smaller number (3), but copy 6’s sign (-). ![]() If numbers have an unlike sign, subtract the number and copy the sign of the number with higher value. The sign of a number and which number is higher must be considered. ![]() Adding a positive number and a negative number can be tricky. Therefore the answer will move more to the left of the number line.Ĭ. When adding negative numbers, compute it the usual way and copy the negative sign. If we add a positive number to a positive number, the answer is always positive.ī. When adding a positive number, compute it the usual way. 5 Negative five is five places to the left of 0.Ī. 1 The negative sign must be before the number All numbers to the left of zero on the number line are negative numbers. Negative numbers are always accompanied by a negative symbol (-) before a number. Negative numbers are numbers whose value is less than zero. On a number line, a positive number is on the right side of zero. ![]() The symbol for all positive numbers (+) is shown before a number, although the positive symbol is usually left off. Positive numbers are all numbers whose value is higher than zero. Let’s discuss the signs of a number more. Negative numbers are number from 0 going to the left of the number line. From zero, all numbers going to the right side are positive numbers. The sign of a number can be a positive or a negative number, and zero is the midpoint of the number line. Looking at this number line, you will notice that it consists of numbers with a sign and zero.
