I sat for an employment test today and candidates were given ten(10) minutes to discuss the above subject.

It depends on the perspective with which an individual wants to view the equation.For instance,if we were to look at it from mathematics angle,then the following conditions would apply:
(1) The number bases you are working with.If it were to be base ten,then the answer would be 2.However,if it were to be base two,the answer would be "10"(pronounced one-zero)
(2)The operation the "cross" symbol represents.That is,the concept of binary operation would be looked at.In binary operation,the cross or plus sign is not regarded as the "normal addition" operator.Any sign that comes in-between two numbers in binary operation is often expressed as "operation". For example, 1+1 is read as "one operation one". Of course, in binary operation if the plus sign actually means addition,then one of the rule would apply;1+1= 1.
Again, if the equation is to be looked at from social perspective,then the institution of marriage would come to mind.In marriage: 1+1=1
Just my contribution.

2 end. TT

According to my primary school teacher (-1 + 1) is impossible, but (1+1) one plus one

In Arithmetics 1+1 = 2
In bedmatics 1+ 1= 1
In business 1+1= 11 ......Ask Dangote.
In election rigging 1+1= 11,100 votes ....Ask PDP.

hmmm dats quite confusing though

If u ask me I'll say 11 sha #dnt blame me, blame ASUU vs FG royal rumble

1+1=0..no one is above normal!

The question is: Negative 1 plus positive 1

Not

Positive 1 plus positive 1

There is an irony to your question. To justify the statement without evidence to support the justification is as relevant as the statement itself.
so if there isn't more to the question.

Answer should be 1

WTF!!!!!!!

Don't forget to take urn alomo with you

remember, an employee or drinks works better

Hmmm... strange question tho, @OP, please don't quit the thread without dropping a solution. These are things we want to see at the front page not Tonto Dikeh...

Its 1 na,meanin u nd ur oga go dey close

.unu abiakwa.

1+1= 5ex

See olodo dem.
The answer is "wanti one"

in mathematics, -1+1=0
but in dis case -1+1 = >1 or <1..
Think deep and u'll undstand wot i mean

...

what kind of question is this?
hell no, I will tell him I don't know it.

The portion in bold is just semantics, even in base 2, the equivalent would be the same magnitude.

10 = (1*2^1)+(0*2^0) = 2 in base 10.

If that were to be the case, we might as well use other bases, not just 2 and 10, meaning we'd be answering for a while.

I like the marriage one though, but all in all, I feel it's a somewhat dumb question.

Good point from SilaV, if it was probability the answer would be 1 because probability of independent & certain events remains certainty A.K.A. 1

U can make it whatever u want it to be, but u'll need to give another answer apart frm 2. Cos their aim is to look for someone who think outside the box

-1+1=0...coz it cancel each oda

1+1= whatever you choose to define it.

Like earlier stated, it depends on the operating base of computation.

An example of what I mean is this:
1, 2, 4, ? What's the next number in the series?

This is a common math problem and on lower level of thinking, it is safe to assume this is a GP series and then conclude the next number is 8.

However looking deeper, the next number could be 17/3.

(1x5 -3)/1 =2
(2x5 -3)/2 =4
...
So third term will be (4x5 -3)/3 =17/3

Point is: when asked such a question, technically the right answer is to ask the condition.

yes. Don't forget binary operation notion, the marriage idea, then our normal base ten addition.

U can make it whatever u want it to be, but u'll need to give another answer apart frm 2. Cos their aim is to look for someone who think outside the box . I'll give like 4 different answers and reasons why it could be any of the 4

ur interviewer just wants to know if u can talk intelligently. That is all. Theres no right or wrong answer. i'll go with the bigger than the sum of our parts narrative and use examples(effective teams blah blah blah) if i were on the hot seat. just basically shooting the rag for 5-10 minutes without breaking a sweat

Still a dumb interview question in my opinion.

So after learning algebra, calculus and all those complicated crap in secondary school, it's 1+1 they're asking now. End time things indeed

In management system 1+1=3
