A numerical expressions operations and steps are found in its words that detail the process
Look at the grouping symbols to discover which calculations must be done before another
Let's see what I mean with a few examples a few numerical expression samples
But first a solo on the bongo
Let's go
What's four times the quotient of twenty and ten
Before we multiply we need to find the quotient
We put brackets around twenty divided by ten
Get four times two eight answers the question
To write and interpret numerical expression we read them closely and ask these questions
What operations are described in this problem
And what's the order in which we will solve them
What's ninety divided by the difference of fourteen and five
Fourneen minus five gives brackets the difference is nine
The next step is symbolized by the division sign
Divide ninety by nine and ten's the quotient we'll find
Let's see an example one more time with the best rhymes you're ever ever ever gonna find
But first a solo on the bongo
Let's go
What's ten times the sum of forty and fifty-three
First put forty plus fifty-three
In parentheses the words tell us to add and get ninety-three first
Then multiply by ten to end the verse
To write an inter-numerical expression we read them closely and ask these questions
What operations are described in this problem
And what's the order in which we will solve them
Let's go
When math class is in session and we read a numerical expression
word clues can help us choose the operations so we can make the correct calculations
Plus all together and all total the sum
These are all clue words for addition
How many more minus remain few with difference
Are all clue words for subtraction
Are all clue words for multiplication
How many times divide goes into quotient
Are all clue words for division
To write and interpret numerical expression we read them closely and ask these questions
What operations are described in this problem
And what's the order in which we will solve them
Thank you for watching
