0 Guest Posted November 13, 2008 Report Share Posted November 13, 2008 Don't really get what you mean, but the solution to 8+9/7-3*12 is: 8+9/7-3*12= 8+1.29-36= 9.29-36= -26.71 You also made a mistake in your calculation: 8+9/7-3*12 pemdas s1.(3*12=36.00) s2.(9/7=1.29) s3.(8+9=17.00) s4.(7-3=5.00) 7-3= 4.00 s5.(36.00+1.29+17.00+5.00=59.29) 36.00+1.29+17.00+4.00=58.29 answer:total average 59.29 58.29 Quote Link to comment Share on other sites More sharing options...
0 Izzy Posted November 13, 2008 Report Share Posted November 13, 2008 (edited) So... you just want us to solve those problems using PEMDAS..? Which we would have done anyways 'cos it's like basic laws of maths? Or does it mean something other than what it normally does?
