Math question: What is the sum of all the digits in the number 248?

To find the sum of the digits in 248, we add up the individual digits: 2 + 4 + 8 = 14.

Math question: If 248 is a triangular number plus 6 times a square number, find the possible values for the triangular number and the square number.

Let's represent the triangular number as x(x+1)/2 and the square number as y^2. According to the problem, we have the equation x(x+1)/2 + 6y^2 = 248. Simplifying, we get x^2 + x - 12y^2 - 496 = 0. This equation suggests that we are searching for integer solutions (x,y). To solve it, we can use techniques like factoring, completing the square, or the quadratic formula. After finding the possible values for x, we can substitute them back into the equation to solve for y. The potential solutions (x,y) will give us the pairs of triangular and square numbers satisfying the given conditions for 248.
