Expanded Notation of 2784 = (2 x 103) + (7 x 102) + (8 x 101) + (4 x 100).
4,768 = (4 x 103) + (7 x 102) + (6 x 101) + (8 x 100)
Powers are a convenient shortcut for repeated multiplication.
Expanded Notation of 525 = (5 x 102) + (2 x 101) + (5 x 100).
Expanded Notation of 1,294 = (1 x 1,000) + (2 x 100) + (9 x 10) + (4 x 1)
The structuring of expressions is to arrive at the correct answer. Using the 'Order of Precedence' : 1. Brackets; 2. Powers and Roots; 3. Multiplication and Division; 4. Addition and Subtraction, ensures that the correct answer is arrived at.
(4 * 103) + (7 * 102) + (6 * 101) + (8 * 100).
4,768 = (4 x 103) + (7 x 102) + (6 x 101) + (8 x 100)
6,125 = (6 x 103) + (1 x 102) + (2 x 101) + (5 x 100)
