Koerarmoca Posted March 21, 2013 Share Posted March 21, 2013 No matter what every.single.day. we end up with one problem that we can not solve. So I took Alg 1 in 7th grade and it came so easy to me. Which was many moons ago but its bugging me that everyday something trips me up. Out of 16 problems dd got 15 correct and I also did them all (for my own practice) we both missed the same one 80+(8x4) Divided by 2 = 96 I have worked this a few ways and still can't get to 96... someone please show me how! or prove the answer key is wrong I am not confident enough to call a key wrong lol.

Alice Posted March 21, 2013 Share Posted March 21, 2013 80 + (8x4) Divided by 2 (I’m assuming there was a division sign where you wrote divided by,I can’t find one on my keyboard either) You do parentheses first so 80 + 32 divided by 2. Then you do all multiplication/division going left to right so 80 + 16 Then you do all addition/subtraction going left to right so 96.

Koerarmoca Posted March 21, 2013 Author Share Posted March 21, 2013 jeeeze... i only looked at it 100 times 8x4 is 32, divided by 2 is 16 + 80 = 96 Quote Link to comment Share on other sites More sharing options...
