write the number in expanded form.
2) 20, 397
Expanded form is to write split up the number into parts each represented by one digit.
421 in expanded form will be
400 + 20 + 1
while 12.47 in expanded form is
46,182=40,000 + 6,000 + 100 + 80 + 2
I will leave #2 for you as an exercise.
I need help with using an expanded algorithm. The problem is 27 times 3 equals 21. Well it does not really equal that but 7 times 3 equals 21 right. Soooo that's why the problem is that and the answer is that. And blank blank plus blank blank. Soooo if someone knows the answer then tell me.
