This means that due to excessive spending and compounding interest accrued, the United States' national debt has escalated astronomically over the past several decades. In the second section, you used the United States' national debt to explore concepts involved with numbers in scientific notation. Use the national debt table to create your own operations with numbers in scientific notation.
