This topic focuses on converting expanded form numbers back into their standard numerical forms. It introduces learners to place value concepts, handling digits and their positions at a basic level, specifically with two-digit numbers. The problems help students understand how to correctly combine tens and unit digits to form two-digit numbers, reinforcing their knowledge of place value and elementary arithmetic. Each question presents a simple addition task that involves two components (tens and units), and then asks to deduce the correct two-digit number from multiple choices provided.
