    The number is 5050 and the solution is to add all the numbers from 1 to 100. This can be done by adding the first and last numbers (1 + 100 = 101), the second and second-last numbers (2 + 99 = 101), the third and third-last numbers (3 + 98 = 101), and so on until you reach the middle number (50 + 51 = 101). You can then multiply the total of 101 by the number of pairs (50) to get the answer 5050. This can also be achieved using brackets by adding all the numbers in the following way:

    (((((((((((1 + 2) + 3) + 4) + 5) + 6) + 7) + 8) + 9) + 10) + ... + 100) = 5050

Do you know the answer?
