RIDICULOUS ! Lmao why did i said that zzz really pissed me off -.- ...
There was this student ask me maths question, its on rate on conversion. The question states : The distance from the Sun to Earth was 1.5 X10^11 metres, how long does light takes to reach Earth? Light travels 1 m in 33 nanoseconds. which is 3.3 X 10^-9. Find time .
The teacher's answer was : (1.5 x 10^11) x (3.3 x 10^9) = 495s (but the answer is 4950s)
1st mistake: answer wrong nvm BUT !!! she wrote 3.3X10^9 WHICH IS WRONG ^%#%^ should be 3.3 X 10^-9 ZZZZ >.<''' she left out the negative in the 9...
2nd mistake: to get time is distance/speed but what the hell did she do? she distanceXspeed SO CLEVER !!
3rd mistake: the next answer i saw was 4.95 x 10^20 = 495seconds ?? LOL damn it man.
4th mistake: 33X10^-9 how on Earth can become 3.3X10^-9? should be 3.3X10^-8 -.-
Disgrace LAAA ... Let me announce her big name only BM students know - MrsLim ^^ that was the test question and know what?? out of 40+ students only 4 passed o.o I had rather she fire herself than making the principal fire her -.- Lucky my maths teacher wasn't her thank god :)
