110 times 10 + 5 - 2 times 7 + 4

Question

how do I solve this expression

Answer 1

Question: Solve the expression 110 times 10 + 5 - 2 times 7 + 4.

 

Comments: This question needs to be specified further for you could get two different solutions for it.

 

Solution 1:

First, rewrite the expression and then use order of operations.

Hence you should write 110 x 10 + 5 - 2 x 7 + 4.

Next, using PEMDAS, you get (110 x 10) + 5 - (2 x 7) + 4.

Note I used parenthesis to help break it down for you but it could as well be done even without using parenthesis or brackets.

So it turns out to 1100 + 5 - 14 + 4.

Then you get 1100 + 5 -10 which simplifies to 1100 - 5.

So your answer is 1095.

 

Solution 2:

Another student may argue using the following facts.

Using parenthesis as the following.

(110) (10 + 5 - 2) (7 + 4)

This simplifies to 110 x 13 x 11

So the answer here is 15730.
