what is the difference between negative and minus
there is no difference bro
i dont think there is its the same
well i just watched a (logic) lecture where the professor stressed that the difference was important, even thought he failed to explain what is was
negative is a state, minus is a operator
they are basically the same though
Negative means false
it can be true also, if the original is false hehe in logic, id like to think, negative as opposite direction, and minus is just a removal of some part, from the whole
i think ganesh is right, you can say theta squre root of a negative numbers is not defined, but you can't say that square root of minus number or minus of a numer is not defined, so you can't use negative and minus synonymously.
sry its that the instaed of theta in previous comment
so a minus requires a reference point?
@UnkleRhaukus yes obviously minus would require a refrence point as far as i know.
and in the case that no reference pint has been specified , why can't we always assume it is zero?
you can always assume that, but the only point i tried to make was that minus and negative can't be used interchangibly,
so you can't say they are the same
what is a single example where it matters ?
suppose b is positive, negative b means, b IS negative minus b means, b is positive, but we just removing the quantity b from ?
from the origin-al zero
yes from the original zero, its a must i guess when we talk negative numbers to take 0 as reference hmm
minus is the actual operation of subtracting numbers. The negative sign indicates the integer. For example 5 - (-3). The - in the middle is the minus and the - in the bracket would be the negative. You could consider them as being the same honestly. If you look at 5 - 3, it could be re-written as 5 - (+3) and so on.

though, with reference to 5, the top quantity is less, its not a -ve state. where as, the bottom quantity IS in -ve state. coz its in opposite direction.
well there is a grammatical difference atleast.. suppose you have 5 and 3 5 minus 3 makes sense,, but 5 negative 3 ? will that be right ?
negative makes a number opposite of positive of positive and minus is the reason a question is subtraction
i think minus is a algorithms ,and negative is a description of the results of this algorithms
