How is place value used to model and find products when multiplying two digit numbers.

On seeing the place value of unit digits, we first multiply the unit digits.

If there is a carry over, we add it with the product of unit digit of the first number with the tenth digit of the second number. We accomplish this task by seeing the place values at the respective digits.

Then, we multiply the tenth digit of the first number with the unit digit of the second number by seeing their place values and repeat the process we did before.

By this way, place values are useful for multiplying two digit numbers.

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
