<s>[INST] Could you please calculate this equation, as well as show your working and why: 8/2(2+2) [/INST] Sure
The answer is 16.

This question can be hard as it contains an implied multiplication. Though if we restructure the equation to show the multiplication it becomes a bit more clear.
Reforming the equation to include the implied multiplication  looks like this:
8/2 * (2+2)
Now we can approach the equation using the mnemonic PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to determine the order of operations.
First, we evaluate the Parentheses.
8/2 * (2+2)  = 8/2*(4)
Then we perform multiplication and division from left to right, thus giving us:
8/2*(4) = (4)*(4) = 16

Thus we get the result of 8/2(2+2) = 16

If your intent was to have the addition happen first, then have the multiplication happen second, and finally, have the division last, you would need to use more parentheses to explicitly show the order of operations. For example, this is what the equation would look like if we rewrote it to do addition first, multiplication second, and division last.
8 / (2 * (2 + 2))
This makes it clear that you want addition first, multiplication second, and division last. </s>
