How to multiply integers

Find the factors of 128 to simplify the term.

We can rewrite the expression as the square roots of these factors.

Simplify.

Multiply the rate of travel (210 mi/hr) by the time traveled (5 hours), and you get the total distance, 1050 miles.

distance = rate * time

distance = (210mi/hr)(5hr)

distance = 1050mi

Start by finding factors for the radical term.

We can rewrite the radical using these factors.

Simplify the first term.

Plug in 7 for x and 5 for y, giving you 5(7) + 3(9). This is equal to 35 + 27, which equals 62.

5x + 3y

5(7) + 3(9)

35 + 27 = 62

Both integers are positive. We just multiply the two numbers. Answer is .

Regardless if the number is positive or negative, anything multipled by zero is always zero. So .

Multiply the ones digits.

Carry over the tens digit, , to the next calculation.

Multiply the seven with the nine, and add the carry over.

Combine these two numbers and the ones digit in our first calculation.

The answer is:

Multiply 91 with the ones digit.

Skip a line and multiply 91 with the tens digit.

Add a zero at the end of this number.

Sum this number with the first number we have calculated.

The answer is:

When multiplying two negative numbers, the answer is positive. Then multiply normally. Answer is .
