Damfash: Appropriately slaughtered. Well done Sir! Where d teacher had d P was in forming d 2nd equation. Instead of 10x + y + 14 = 3xy, d teacher wrote xy + 14 = 3xy leading to xy = 7 thus messing everytin up. |

Horlawale1:'X' has been helping mankind since d days of d tower of babel and pyramid building. Man can't do w/o 'X'. W/o 'X' no computers/internet, no banking system, no space travel, no high-tech comm, no robotics, no automobiles, no satellites, no advanced architecture, structures, weapons, etc. Math has applications in almost every sphere of human endeavor |

Horlawale1:Not abstract, it has everyday applications. Having a sound knowledge of math is not diametrically opposed to being wealthy. Heck, if u don't know math to a level, ur accountants/managers go just dey cheat u black n blue and feed u with biz jargons. Unless na local money u dey find. 1 Like |

emsheddy: Lol. Bros na govt skul so no work for u. Seems d falling standard of education affected both students n teachers cos in my time, govt skul teachers gud die. Some govt skuls look for 'machines' to help their students during O'level math exams whereas they have math teachers in that skul. 1 Like |

Nely77: What's ur answer? |
Re: NECO Math Questions Some Teachers Couldn't Solve by Nobody: 3:26pm On Jun 29, 2016 |
Wealthgang: Not when the sentences describe totally different scenarios and yield different equations. The first step, is to turn the word problem into an algebraic equation so it's crucial. The distinction had to be made in GMAT because the error is quite commonly made. Probably because teachers were asked not to be too pedantic when giving lessons at O'levels. |
