Question

(2-1) + (4-3)+(6-5)+ ... (2014-2013) = ?

Answer 1

2-1=1
4-3=1
6-5=1
2014-2013=1
1+1=2
2+1=3
3+1=4

Answer 2

To find the value of the expression (2-1) + (4-3) + (6-5) + ... + (2014-2013), you can simplify each term first and then sum them up:

(2-1) + (4-3) + (6-5) + ... + (2014-2013) = 1 + 1 + 1 + ... + 1

Now, you have 1 repeated multiple times. The number of times you have 1 is equal to the number of terms in the original expression. You can find this by calculating the difference between the highest and lowest numbers and then adding 1 (to include the endpoints):

Number of terms = (2014 - 1) + 1 = 2014

Now, you can sum up the 1s by multiplying 1 by the number of terms:

1 * 2014 = 2014

So, (2-1) + (4-3) + (6-5) + ... + (2014-2013) = 2014.
