Solve the following problem:
Adhering to the rules of the order of operations, the exercise can be solved from left to right, given that it only contains multiplication.
Proceed to solve the left exercise vertically in order to avoid confusion as shown below:
It's important to maintain correct positioning of the exercise, with the decimal point serving as an anchor.
Then we can multiply in order, first the ones digit of the first number by the ones digit of the second number,
then the tens digit of the first number by the ones digit of the second number, and so on.
We should obtain the following exercise:
Remember that:
We will once again solve the exercise vertically whilst maintaining the decimal point and multiplying in order (ones, tens, and so on)
As shown below:
\( 94+12+6= \)
Multiplying two numbers at a time keeps your work organized and reduces errors. It's much easier to handle first, then multiply that result by 7.3.
Count the decimal places in each original number: 11.2 has 1, 5.6 has 1, 7.3 has 1. Your final answer should have 1 + 1 + 1 = 3 decimal places.
You shouldn't! Multiplication is commutative, meaning equals . If you get different answers, check your decimal placement.
Yes, but understanding the step-by-step process helps you catch calculator errors and builds your number sense. Always verify that your answer makes sense!
Breaking it into steps means you only handle two numbers at a time. This reduces mental load and makes it easier to align decimal points correctly in vertical multiplication.
