Squaring A Decimal
Square decimal numbers in Grade 6 math by multiplying a decimal by itself — apply place value rules to count decimal places in the product and verify results.
Key Concepts
Property To square a decimal, you multiply the number by itself. For example, $(2.5)^2$ means you calculate $2.5 \times 2.5$.
Examples $(0.8)^2 = 0.8 \text{ (1 place)} \times 0.8 \text{ (1 place)} = 0.64 \text{ (2 places)}$ $(1.2)^2 = 1.2 \text{ (1 place)} \times 1.2 \text{ (1 place)} = 1.44 \text{ (2 places)}$ $(0.05)^2 = 0.05 \text{ (2 places)} \times 0.05 \text{ (2 places)} = 0.0025 \text{ (4 places)}$.
Explanation Squaring a decimal is just a special case of multiplying! You multiply the number by itself. Use the same counting rule: multiply as if they were whole numbers, then count up the total decimal places from both identical factors. Place the decimal point accordingly. This trick works every single time for any squared decimal!
