When calculating an addition problem, Xiao Ning mistook addition for multiplication and got 1 10. As we all know, these two additions

1 . x 1 = 9.6 x2 = 9.6/ 1.2 = 8 x3 = 7.6 * 3-9.6-8 = 5.2

2.36*0.5-4.5A=0, while A=4.

3. These two numbers are x, y comes from the question x-y= 1, xy= 1 10.

So x= 1 1 y= 10.

Correct result x+y=2 1
