2 cards from this section. Quick, good the night before a test.
What happens when you add 1111 (15) and 0001 (1) in 4-bit unsigned arithmetic?
Think about how numbers are represented in bits.
What is the maximum value representable in 4 bits for unsigned numbers?
Consider the range of 4 bits.
What occurs when an overflow happens during addition in unsigned arithmetic?
Overflow has implications on how numbers are stored.
True or False: The zero flag is set when the result of the addition is non-zero.
Think about the condition that sets the zero flag.
Two unsigned numbers, 0101 and 1010, are written in 8-bit binary. Perform addition and explain each flag behavior after the operation.
Always check the binary results and their implications.
Consider the binary addition of two maximum values in 4 bits. Discuss what happens with various flags.
Identify what would normally happen with each flag when you reach technical limits.
