This math topic focuses on converting numbers from expanded form to standard (normal) form, specifically dealing with large numbers up to millions and thousandths. Students are asked to recognize the value of individual digits based on their place in a number, and then to combine these values to construct and identify the correct seven-digit number. Each problem provides partial sums (in millions, thousands, hundreds, etc.) that must be correctly added to form the final number. The exercises help to reinforce understanding of place value and the complexity of large numbers.
