What happens when you multiply numbers with different variables?

When multiplying variables, you multiply the coefficients and variables as usual. If the bases are the same, you can multiply the bases by merely adding their exponents.

Do signs change in multiplication?

For Multiplication and Division: If the signs are the same the result is positive. If the signs are different the result is negative. Addition: Note that the magnitude of a signed number is the same as its absolute value. When adding a positive number and a positive number: Add the magnitudes.

Do two positives make a positive?

  • Any number times zero is always zero.
  • Any number times one is always the same number.
  • Add a zero onto the original number when multiplying by 10.
  • The order of factors does not affect the product.

How do you multiply two variables with different terms?

To multiply terms, multiply the coefficients and add the exponents on each variable. The number of terms in the product will be equal to the product of the number of terms.

When you multiply two numbers with different signs the product is negative?

The rule states that if the signs of the two integers are different then the final answer will be negative. Example 2: Multiply the integers below. Solution: Multiply the absolute values of the two numbers. Since we are multiplying integers having the same sign, the final answer (product) should be positive.

When you multiply two negatives do you get a positive?

When you multiply two negative numbers or two positive numbers then the product is always positive. 3 times 4 equals 12. Since there is one positive and one negative number, the product is negative 12. Now we have two negative numbers, so the result is positive.
