Multiplies To _ And Adds To _ Calculator - TimTech Software

CategoriesPublic Domain

If you have the sum of two numbers as well as the product those numbers, you can use this online calculator to calculate the actual numbers for you:

macalc2

This is especially useful for factoring trinomials, such as x2+7x+12, by entering the coefficients into the calculator. For example, if you make X*Y=12 and X+Y=7, then you find that X=4 and Y=3. You can then rewrite the trinomial in its factored form, (X+4)(X+3).

If you need any help, simply leave a comment below and I’ll see what I can do.

    Are there any two numbers that multiply to 7 and add to 0? It’s probably an easy answer but I’m just not good at math.

    Reply
    • Timtech October 14, 2019 @ 12:28 PM

      No, there aren’t. Think about it like this:

      Any two numbers that add to zero must be equal, but opposite in sign. For example, 2 and -2, 3 and -3, etc. One of them will be positive, and the other will be negative.

      Thus, when you multiply these numbers together, you will never get a positive answer, since the product of a positive and a negative number is always negative.

      This is impossible; in order for two numbers to add to zero, one must be positive and one must be negative. When you multiply a positive and a negative number, you will always get a negative answer.

      Consider that 1 * 6 = 6, and 2 * 3 = 6. Now, one of these numbers must be negative, so that you can get -6.

      2-3 = 5, nope. 3-2 = 5, nope. 1-6 = 5, nope. 6-1 = 5, yup. Therefore the numbers are 6 and -1.

      Think about all of the possible ways to get 75 by multiplying: (1 * 75), (3 * 25), and (5 * 15). Of course, one of these numbers must be negative, so that you can multiply to get -75.

      Now, the numbers must add up to 22. We can see that 25 is fairly close to 22. In fact, 25 minus 3 gives us 22. Therefore we know that 25 * -3 = -75 and 25 + -3 = 22.

      You probably already realized that no two real numbers can multiply to 13 while still adding up to 6. You are looking for the complex numbers 3+2j and 3-2j, where j represents the imaginary unit. You can check these numbers like so:

      ( 3+2j ) + ( 3-2j ) = ( 6+0j ) = 6 ( 3+2j ) * ( 3-2j ) = ( 9 + 6j – 6j + 4) = 13

    what adds up to 112 for the problem For the end-of-year party, Mt. Rose Middle School ordered pizzas. There were eight fewer veggie pizzas than there were pepperoni pizzas. There were three times as many combo pizzas as pepperoni pizzas. Use the 5-D Process to define a variable and write an equation for this situation. Then determine how many of each kind of pizza were ordered.

    Reply
    • Timtech October 24, 2021 @ 7:14 PM

      Hi Mackenzie, to begin the 5D process, we need to define variables that represent the information that we already know. Let’s use the letter V to represent the number of veggie pizzas, P for pepperoni pizzas, and C for combo pizzas. With these letters, we can “Define” equations based on the information given in the problem:

      V + P + C = 112 V + 8 = P C / 3 = P

      I hope that this provides you with a good start for this problem. Once you go through all 5 steps, you should be able to “Declare” that Mt. Rose Middle School ordered 16 veggie pizzas, 24 pepperoni pizzas, and 72 combo pizzas.
