Froggy Jumps Binary Addition QuizOnline version Test your knowledge on adding binary numbers and avoiding overflow errors. by Miss Pixie 1 What are the four rules for adding binary numbers? a 1 + 0 = 0, 0 + 1 = 1, 1 + 1 = 10 with a carry of 1, and 1 + 1 + 1 = 11 with a carry of 1 b 1 + 0 = 1, 0 + 1 = 0, 1 + 1 = 11 with a carry of 1, and 1 + 1 + 1 = 100 c 1 + 0 = 1, 0 + 1 = 1, 1 + 1 = 10 with a carry of 0, and 1 + 1 + 1 = 11 with a carry of 0 2 When can overflow errors occur when adding binary numbers? a When adding 1 + 0 in the middle column b When adding 1 + 1 in the last column c When adding 0 + 0 in the first column 3 What happens when an overflow error occurs in binary addition? a The carried 1 is added to the next column b The carried 1 is subtracted from the previous column c The carried 1 has nowhere to go and is lost, resulting in the wrong answer 4 How can overflow errors be avoided in binary addition? a By using a 8th bit b By using a 10th bit c By using a 9th bit 5 What is recommended to check the answers in binary addition? a Converting them to octal at the end b Converting them to hexadecimal at the end c Converting them to denary at the end 6 What is the result of 1 + 0 in binary addition? a 1 b 0 c 10 7 What is the result of 0 + 1 in binary addition? a 10 b 1 c 0 8 What is the result of 1 + 1 in binary addition? a 0 b 11 with a carry of 0 c 10 with a carry of 1 9 What is the result of 1 + 1 + 1 in binary addition? a 11 with a carry of 1 b 10 with a carry of 0 c 0 10 How many bits are needed to avoid overflow errors in binary addition? a 8 b 9 c 10
