It is quite easy. Try to follow this example.
01100111
01010011
=
10111110
Method : Same as in Decimal system, but highest possible number is 1.
Start at the last digits
First place is 1+1 = 0 and carry one
Second place is 1+1+the CarryBit 1 =1 and carry one.
Third place is 1+0+the CarryBit 1 = 0 and carry one.
Fourth place is 0+0+the CarryBit 1 = 1 and carry zero.
Fifth place is 0+1 and No CarryBit = 1 and carry zero.
Sixth place is 1+0 and No CarryBit =1 and carry zero.
Seventh place is 1+1 and No CarryBit = 0 and carry one.
Eighth place is 0+0 + the CarryBit 1 = 1 and carry none.
Cheers.

Binary numbers, with or without a computer are a series of 1's and 0's.

A computer works in binary, meaning that a computer interprets everything as simply 'on' or 'off', and recognizes two numbers: zero and one.
A binary number is a number that consists of only 0 and 1. We use decimal numbers, which consist of numbers made up from 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. The decimal system is also known as the denary system. Binary is critical to how computers operate, but that would take time to explain in detail. For your examples that you asked for, the following is how binary and decimal represent numbers from decimal 0 to decimal 10. 0 = 0 1 = 1 10 = 2 11 = 3 100 = 4 101 = 5 110 = 6 111 = 7 1000 = 8 1001 = 9 1010 = 10
twos compliment binary Each of its capacitor memory drums stored 30 fixed point 50 bit twos compliment binary numbers (totaling 60 numbers of roughly 14 digit precision). Note: the ENIAC could only store 20 fixed point numbers of 10 digit precision as a comparison (using decimal numbers). Both machines could only do additions and subtractions (although ENIAC had special hardware implementing algorithms for multiplication, division, and square roots by performing sequences of additions and subtractions and was programmable to solve different problems, while the ABC performed only the single function of solving large systems of simultaneous equations).
