Operations with Signed Numbers Worksheets
What Are the Rules for Operations with Negative Numbers? Fractions, whole numbers, and real numbers can all be positive and negative. Any number greater than zero is known as the positive number and numbers less than zero, are known as the negative numbers. You can perform every mathematical operation on negative and positive numbers or even by combining both the numbers. Addition  When adding a negative number with another negative number, we add them and give them the same sign. For example, when we add (4) + (2)   4 2 = 6 . However, when adding a positive and negative number we perform subtraction and assign the sign of the greater number. For example, (4) + 2 = (2). Subtraction  For subtraction, we switch the sign of the number to it is opposite sign and add or subtract them. For instance, when subtracting a negative number from a negative, like 5  2, change negative 2 to positive 2 and the add the numbers. This will give you 5 + 2= (3). Multiplication  When multiplying positive with positive or negative with negative, we do not change the sign. However, when we multiply numbers with opposite numbers (positive with negative), we always assign the negative sign. Division  When we divide two positive numbers, we keep the positive sign. And when we divide negative with a positive number or positive by a negative number, we always put the negative sign.
