Binary Arithmetic Rules Reference

Understanding the fundamental rules of binary arithmetic helps users verify calculator results and build intuition for base-2 mathematics.

Addition Rules:

• 0 + 0 = 0
• 0 + 1 = 1
• 1 + 0 = 1
• 1 + 1 = 10 (0 with carry 1)
• 1 + 1 + 1 = 11 (1 with carry 1)

Subtraction Rules:

• 0 - 0 = 0
• 1 - 0 = 1
• 1 - 1 = 0
• 0 - 1 = 1 (borrow 1 from next position)

Multiplication Rules:

• 0 × 0 = 0
• 0 × 1 = 0
• 1 × 0 = 0
• 1 × 1 = 1

Binary multiplication follows the same long multiplication method as decimal, but simpler since only two digits exist.

Binary-Decimal Conversion Guide

Binary to Decimal Method: Each binary digit represents a power of 2, starting from 2⁰ on the right. Add the powers of 2 where the binary digit equals 1.

Example: 1011 = (1×2³) + (0×2²) + (1×2¹) + (1×2⁰) = 8 + 0 + 2 + 1 = 11

Decimal to Binary Method: Repeatedly divide the decimal number by 2 and record the remainders. Read the remainders from bottom to top.

Example: 13 ÷ 2 = 6 remainder 1, 6 ÷ 2 = 3 remainder 0, 3 ÷ 2 = 1 remainder 1, 1 ÷ 2 = 0 remainder 1 Result: 13 in decimal = 1101 in binary

FAQ Section

What is a binary calculator and how does it work?

A binary calculator performs arithmetic and logical operations on numbers expressed in base-2 format using only digits 0 and 1. It applies the same mathematical principles as decimal calculators but follows binary rules where carrying occurs at 2 instead of 10.

Can I perform all four basic arithmetic operations?

Yes, the calculator supports addition, subtraction, multiplication, and division of binary numbers. Each operation follows standard binary arithmetic rules with proper handling of carries, borrows, and remainders.

What are bitwise operations and when should I use them?

Bitwise operations (AND, OR, XOR, NOT) compare or manipulate individual bits within binary numbers. Programmers use them for tasks like setting flags, masking values, encryption, and optimizing performance-critical code.

How do I convert my binary result to decimal?

The calculator automatically displays results in binary, decimal, and hexadecimal formats simultaneously. No manual conversion is necessary. You can also use the unit converter for additional conversion needs.

What is two's complement and does this calculator support it?

Two's complement is a method for representing negative numbers in binary where the most significant bit indicates the sign. Yes, the calculator supports signed binary arithmetic using two's complement representation.

Is there a limit to how many digits I can calculate?

The calculator handles binary numbers of practical lengths used in computing, including 8-bit, 16-bit, 32-bit, and 64-bit values. Most operations complete instantly regardless of bit length.

Why do I get different results for signed vs unsigned calculations?

Signed calculations interpret the leftmost bit as a sign indicator, making numbers with a leading 1 negative. Unsigned calculations treat all bits as magnitude, giving larger positive values for the same bit pattern.

Can I use this for homework and academic assignments?

Absolutely. The step-by-step solutions help students understand binary arithmetic processes. Teachers often recommend calculators for verification after attempting manual calculations.

How accurate are the calculation results?

Results are 100% mathematically accurate following standard binary arithmetic rules. The calculator uses precise integer arithmetic without floating-point rounding errors.

What's the difference between binary and hexadecimal?

Binary uses base-2 (digits 0-1) while hexadecimal uses base-16 (digits 0-9 and A-F). Each hexadecimal digit represents exactly four binary digits, making hex a compact representation of binary values.

Can I perform operations between binary and decimal numbers? Enter numbers in binary format only. Convert decimal numbers to binary first if needed, or use the conversion feature to work between systems seamlessly.
