What is Estimating Decimal Sums and Differences about?

Rockwoods High School was teaching a mathematics lesson on estimating sums and differences of decimals. The lesson aimed to help students learn how to estimate sums and differences by rounding decimals to the nearest tenth or whole number. As an example, students were asked to find the total approximate percentage of carbon dioxide and nitrogen in air, given that carbon dioxide was 1.366% and nitrogen was 2.499%, by rounding to the nearest tenth.
