Multiply the given algebraic terms by combining coefficients (numbers) and variables (letters), using the rules of algebra:
- Multiply the numerical coefficients.
- Combine like variables by adding their exponents (e.g., $ x \times x = x^2 $).
- Keep unlike variables as separate terms.

- Multiplying coefficients: Just multiply the numbers together.
- Variables: When multiplying variables, write them in alphabetical order (optional but standard), and combine like bases by adding exponents (though here most are single powers).
- Order doesn't matter due to commutative property: $ ab = ba $.
- Decimal numbers are treated just like whole numbers.
