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

The highest place in the lowest number is thousands, so
9103 becomes 9000
12545 becomes 13000
adding, 22000 
can you help me with my homework

yes
