60 -15 = 45
(1/2) + (2/5) - (1/2)(2/5) (5/10) + (4/10) - (2/10) (9/10) - (2/10) = (7/10) 7/10 = the difference
30 x 10 = 300. 75 + 75 = 150. Their difference is 150.

It is 0.5
20 + 10 = 30 20 x 10 = 200 200 - 30 = 170 Your answer is 170.
(1/2) + (2/5) - (1/2)(2/5) (5/10) + (4/10) - (2/10) (9/10) - (2/10) = (7/10) 7/10 = the difference
sum = 10 1/2 product = 5 difference = 51/2
It is: (20*10)-(20+10) =170

3 & 7? Sum 10, difference 4 so ratio 5:2 or 1 & 21? Sum = 22, difference 20 so ratio 11:10
The product of 3 and 7 is found by multiplying the two numbers together, which equals 21. The sum of 3 and 7 is found by adding the two numbers together, which equals 10. Therefore, the difference between the product of 3 and 7 and the sum of 3 and 7 is 21 - 10 = 11.
7x + 10
The difference of two squares is equivalent to the sum, times the difference, of the numbers that are squared. In symbols: a2 - b2 = (a + b)(a - b) Here is an example with numbers: 102 - 92 = (10+9)(10-9)
The integers 2 and 10 have a product of 20 and a sum of 12.
