Halving and negative numbers

C is pretty good at halving numbers, although we stumped her tonight with "What is half of 98?" She knows what half of 1,000 is, and what's more, she was able to tell us what half of 1,050 is. My husband was also asking her simple arithmetic questions with negative answers. She correctly answered problems like 1 minus 2 and 10 minus 15. I am very pleased.
