Komposisi dan dekompesisi bilangan cacah sampai 10.000

This material discusses how to compose and decompose whole numbers up to 10,000 based on their place values. Students learn to form numbers from a combination of thousands, hundreds, tens, and units, and decompose a number into place value form, for example 5,432 = 5,000 + 400 + 30 + 2. Understanding composition and decomposition helps students understand number structures better and becomes an important basis in arithmetic operations and solving mathematical problems.
