I have been browsing around for hours and trying different things to first convert the integer to binary. Press question mark to learn the rest of the keyboard shortcuts. Most students recognize that a decimal number can be extended by adding a 0 to the left of a decimal number, which does not in any way change that number. A:Introduction: If you want to work with other number bases, like base 10, you'd need to do actual division (MIPS divu) or remainder to remove or isolate the lowest base-10 digit.
