Some timesaving tips for multiplication are to follow a certain order when multiplying two decimal numbers. In general, the first number is multiplied by 10 and the second number is multiplied by 100. So, if one decimal number is 9.5 and the other is 1.6, then the correct calculation would be: 9.5 × 10 = 95, and 1.6 × 100 = 160.
Another tip is to use a table or equation when doing multiplications. This can help you remember the order of operations (parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). For example, if you wanted to multiply 3 numbers together, you might use an equation such as: 72 + 56 + 12 = 180. So long as you understand what each term in the equation corresponds to, you can solve it easily with a calculator or trigonometry worksheet!
