Arithmetic Binary Shifts

Arithmetic Binary Shifts

Multiply and divide binary numbers through bitwise arithmetic shifts

Multiple Select

In this lesson you are going to learn how to ....

• apply arithmetic bitwise shifts to signed binary numbers

• describe difference between an arithmetic right shift and a logical right shift

• apply logical shifts to binary numbers

• describe difference between a logical left shift and right shift

Multiple Select

Choose two statements that are True about an arithmetic LEFT shift operation ...

• The MSB is shifted left and out

• A 0 is shifted in to become the LSB

• The MSB is shifted right and out

• A 0 is shifted in to become the MSB

Multiple Choice

True or False:

Left arithmetic shifting is the same as left logical shifting

• True

• False

Multiple Select

Choose two statements that are True about an arithmetic RIGHT shift operation ...

• The MSB is always retained

• The LSB is always lost

• The MSB is shifted right

• The LSB is always retained

Multiple Choice

True or False:

Right arithmetic shifting is the same as right logical shifting

• True

• False

Multiple Choice
