Given: \(5+1\times10\) When an expression contains both a sum and product without any brackets, then we always neet to perform the product before performing the sum. This is thus equivalent with placing brackets about the product.

\(=5+(1\times10)\)

Let us evaluate the product using that the product of 1 and 10 is 10.

\(=5+10\)

Next, we evaluate the sum using that the sum of 5 and 10 is 15:

\(=15\)

Thus the answer to the equation is 15.
