Following BODMAS rule, 9 - 4 + 1 should give me 4. I run same on Javascript console it returned 6 instead. Help, What am I missing? |

stevedeey:bodmas is for mathematics. In javascript and programming operations move from left to right so its is 9-4 = 5 then +1 which is 6 |

stevedeey:9-4+1 does not give you 4 mathematically It only gives you 6. Except you mean 9 - (4 + 1) The verbose version of your calculation would be +9-4+1 This means all numbers carry a sign at their front. So it would be wrong for you to assume 4 + 1 instead of -4 +1 which is more accurate 7 Likes 1 Share |

Thanks so much @contributors. I realised to get 4, I'd need to introduce brackets 3 Likes 1 Share |

stevedeey:using Bodmas, the result will still be 6 . It is -4 + 1 = -3. Then 9 - 3 = 6. Not 4 + 1 = 5 then 9 -5 = 4. So you applied bodmas wrongly. 1 Like |
