This simple rule is the order of operations which states that multiplication precedes addition and subtraction, and division precedes all of them,
In the given example, a multiplication occurs between two sets of parentheses, thus we simplify the expressions within each pair of parentheses separately,
We start with simplifying the expression within the parentheses on the left, this is done in accordance with the order of operations mentioned above, meaning that multiplication comes before subtraction, we perform the multiplications in this expression first and then proceed with the subtraction operations within it, in reverse we simplify the expression within the parentheses on the right and perform the subtraction operation within them:
What remains for us is to perform the last multiplication that was deferred, it is the multiplication that occurred between the expressions within the parentheses in the original expression, we perform it while remembering that multiplying any number by 0 will result in 0:
Therefore, the correct answer is answer d.
\( 0+0.2+0.6= \) ?
Parentheses show grouping - they tell you which calculations belong together! Without solving them first, you'll mix up the order and get the wrong answer.
Great observation! When any factor in multiplication equals zero, the entire product becomes zero. So no matter what the other number is.
Inside parentheses, follow PEMDAS too! Multiplication comes before subtraction, so solve by doing both multiplications first, then the subtraction.
Not in this case! Distribution works when you have something like . Here you have two separate groups multiplied together, so solve each group first.
Use PEMDAS: Please Excuse My Dear Aunt Sally. Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right).
