How can estimating be helpful

nadezda [96]

It helps you narrow down to a smaller answer for example there is pi, (3.14159265359) and there is more and more to that number. It is now estimated to 3.14 because it would be almost impossible to work with pi if it wasn't estimated

Write an expression for the calculation add 3 and 8 and then multiply by 9

melisa1 [442]

Hey there!

Basically it wants you to add 3 and 8 from each other, what ever the answer to that part, you multiply the result by 9

Here this is what i meant

$3 + 8 = 11 \\ 11 ( 9) = 99$

Or you could do this method too!

$(3 +8) (9) \\ \\ 3 + 8 = 11 \\ 11(9) \\ = 99$

They both give you the result of $99$

So, I am assuming your expression would look like this: $(3 + 8) * 9$

Good luck on your assignment and enjoy your day!
