Let the two numbers be x and y

The sum of two numbers is 13. Accordingly

x + y = 13…Eq..1

The difference of the numbers is 23,

x - y = 23

x = 23 + y….. Eq. 2

Substituting the value of x from Eq. 2 to Eq..1

x + y = 13

23 + y + y = 13

2y = 13 - 23

2y = —10

y =-10/2

y = —5

The value of one number is —5

Substituting the value of y in Eq. 1 to derive value of x

x + y = 13

x + ( - 5) = 13

x - 5 = 13

x = 13 + 5

x = 18

The value of other number is 18

The value of two numbers are 18 and - 5

Product of these two numbers

= 18 × (—5)

= —90
