(5*SQRT16-3)(2*SQRT10+2) I ASSUME BECAUSE THERE ARE NO () AROUND THE 16 & 10
THAT THIS IS THE PROBLEM?
(5*4-3)(2*3.16+2)
(20-3)(6.32+2)
17*8.32
141.44
___________________________________________
HOWEVER IF THERE SHOULD BE () AROUND THE (16-3) & THE (10+2) THEN
(5SQRT13)(2SQRT12)
(5*3.61)(2*3.46)
18.05+6.92
24.97
