4th grade math homework. rounding sums and differences.
paper say "round each number to its highest place. then estimate the sum or difference."
example says 92 +28=
then says round to 90 and 30 to make 120.
further down numbers get larger
12646 + 9103=
do i round to the tens place or the hundreds place

math 
bobpursley,
The highest place in the lowest number is thousands, so
9103 becomes 9000
12545 becomes 13000
adding, 22000
