Count in ones to subtract. 358 subtract six equals what?
We have to subtract six from
358. And we’re given a number line which
starts at 350 and ends at 360. The question tells us to count in
ones to subtract. When we’re subtracting, we need to
count back along the number line. We need to start at 358 and count
back six. And if we count in ones, we need to
count back six times. One, two, three, four, five,
six.
We started at 358 on the number
line. We counted back in ones six
times. That took us to the number 352. 358 subtract six equals 352. To subtract the six ones from our
three-digit number, we counted back in ones. We counted back six times until we
reached the number 352.
