The arithmetic effect of applying a left binary shift of two to a binary number is to multiply that number by four.
State the arithmetic effect of applying a left binary shift of four to a binary number.

A left binary shift (also known as a logical shift left) moves all bits in a binary number to the left by a specified number of places. For each place shifted, the number is effectively multiplied by 2. Therefore, a left shift of 'n' places has the arithmetic effect of multiplying the original number by 2^n. In this case, n = 4. So, the effect is multiplication by 2^4, which is 16.
