SUM MASTER: Addition Nonogram

GAME INFO
SUM MASTER is an educational math game, an addition nonogram. What is a nonogram? It is a two-dimensional matrix, a table with rows and columns, which has in the headers as a summary a number of each row and column. In this case, the selected boxes must add up to the result marked in each row and in each column. Your mission is to click on the numbers of the matrix so that you complete the sums, taking into account that each number of the matrix participates of the sum of its row and its column. Design your strategy and go for the easy boxes, for example when you only have to mark one number, the same of the row or column, and use reasoning to determine which rows or columns to solve first until you complete the nonogram.
