Find the the sum of the second multiple of 7 the fifth multiple of 100 and the ninth multiple of 10

14 + 500 + ? = ______

I think you do 500+45+14=559

Where did you get 45?

To find the sum of the second multiple of 7, the fifth multiple of 100, and the ninth multiple of 10, we need to calculate each multiple separately and then add them together.

First, let's find the second multiple of 7:
To find any multiple of a number, you multiply that number by the multiple you want. In this case, we want the second multiple, so we multiply 7 by 2.
7 * 2 = 14

Next, let's find the fifth multiple of 100:
Again, we multiply 100 by the desired multiple which is 5.
100 * 5 = 500

Finally, let's find the ninth multiple of 10:
Again, multiply 10 by 9.
10 * 9 = 90

Now, we add all three multiples together to find the sum:
14 + 500 + 90 = 604

So, the sum of the second multiple of 7, the fifth multiple of 100, and the ninth multiple of 10 is 604.
