Operation
11000
Decimal equivalent: 24
Method: column addition with carries 1101 + 1011 ────── Column 1 from right: 1+1+0(carry) = 10, write 0, carry 1 Column 2 from right: 0+1+1(carry) = 10, write 0, carry 1 Column 3 from right: 1+0+1(carry) = 10, write 0, carry 1 Column 4 from right: 1+1+1(carry) = 11, write 1, carry 1 Final carry = 1 Result: 11000 = 24 in decimal
Binary uses base 2, so each position is a power of 2 and each digit is either 0 or 1.
Binary addition works like decimal column addition, but 1 + 1 becomes 10, so you write 0 and carry 1.
Bitwise operations compare or shift individual bits. They are common in programming, networking, flags, and low-level systems work.
This calculator is designed to help you understand the likely number before you make a decision or start an application.
Your result should be checked against official UK guidance, especially if your circumstances include dependants, exemptions, prior leave, or a complex immigration history.
Treat the figure as a planning tool rather than legal advice. Where the answer affects an application deadline or major payment, speak to an authorised adviser.
