what is: +51 + (−50) + (+49) + (−48)?

+51 + (-50) + (+49) + (-48)

= 51 - 50 + 49 - 48

= (51 - 50) + (49 - 48)

= 1 + 1

= 2

Drop the course and go back to kindergarten.

51 - 50 + 49 - 48 =
1 + 1 = 2

(+51)+(-50)+(+49)+(-48)=
(+51*1)+(-50*1)+(+49*1)+(-48*1)=
((+50*1)+(+1*1))+(-50*1)+((+40*1)+(+9*1))+((-40*1)+(-8*1))=
((+5*(10^1))+(+1*(10^0)))+((-5*(10^1)))+((+4*(10^1))+(+9*(10^0)))+((-4*(10^1))+(-8*(10^0)))=

2 is the answer

(51-50)+(49-48)=2

51 - 50 = 1
49 - 48 = 1

1 + 1 = 2

51-50+49-48
=2

51 - 50 + 49 - 48 =
100 - 98 =
2.

its answer is 2.

+ 51 + ( - 50 ) + ( + 49 ) + ( - 48 ) = 51 + * - 50 + 49 + * - 48 , simplification by multiplication of + * - , opening the brackets ( ) , since + * - OR - * + = - and - * - = + , we get
51 - 50 + 49 - 48 = 1 + 1 = 2

51-50+49-48 = 2

It's basically 51-50+49-48 so 51-50=1, 1+49=50, 50-48=2.

That's it

51-50=1
1+49=50
50-48=2

2 I think. Try this

51-50=1
1+49=50
50-48=2

+51 + (−50) + (+49) + (−48).
Combine like terms:
+51 + (+49) = +100 or 100
-50 + (-48) = -98
Then add them together: 100 + (-98) = 100 - 9 = 2.

2. Separate into two different sums (or differences) and you'll see clearly.
