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.
