What are the rules for positive and negative integers?

The Rules:RuleExample+(+)Two like signs become a positive sign3+(+2) = 3 + 2 = 5−(−)6−(−3) = 6 + 3 = 9+(−)Two unlike signs become a negative sign7+(−2) = 7 − 2 = 5−(+)8−(+2) = 8 − 2 = 62 more rows.

What are the 4 operations of integers?

You can perform four basic math operations on them: addition, subtraction, multiplication, and division. When you add integers, remember that positive integers move you to the right on the number line and negative integers move you to the left on the number line.

What is the rule for dividing integers?

When you divide two integers with the same sign, the result is always positive. Just divide the absolute values and make the answer positive. When you divide two integers with different signs, the result is always negative. Just divide the absolute values and make the answer negative.

What are the rules of addition and subtraction of integers?

Rules of integers for addition and subtraction : 1) If the two numbers have different sign like positive and negative then subtract the two numbers and give the sign of the bigger number. 2) If the two numbers have same sign i.e. either positive or negative signs then add the two numbers and give the common sign.

What is the rule for negative numbers?

To get a negative number, you need one negative and one positive number. The rule works the same way when you have more than two numbers to multiply or divide. An even number of negative numbers will give a positive answer. An odd number of negative numbers will give a negative answer.

Do you add two negative numbers?

Adding two negative numbers is easy: you’re just adding two “negative” arrows, so it’s just like “regular” addition, but in the opposite direction. For instance, 4 + 6 = 10, and –4 – 6 = –4 + (–6) = –10.

What happens when you add two negative numbers?

When you are adding a negative number to a negative number, it becomes subtraction, where you start from a negative point on the numbers line and move left. For example, -3 + (-2). … You need to ignore the plus sign and recognize that the second negative means you are subtracting that number.

Which is higher in negative numbers?

On the number line the negative numbers are to the left of zero. –5 is less than 4, because –5 lies to the left of 4 on the number line. –1 is greater than –3, because –1 lies to the right of –3 on the number line.

What are the four rules of multiplying integers?

Multiplication and Division of Integers. RULE 1: The product of a positive integer and a negative integer is negative. RULE 2: The product of two positive integers is positive. RULE 3: The product of two negative integers is positive.

What are the five properties of integers?

Integers have 5 main properties of operation which are:Closure Property.Associative Property.Commutative Property.Distributive Property.Identity Property.

What is the subtraction rule?

Why negative multiply negative is positive?
