We can get two equations: learning × learning = number and number+learning =9. Solve the first equation, learning × learning = mathematics. Assuming that science =a and number =b, then the equation can be expressed as: A× A = B. After further sorting, we get: B = A 2. The number of solving the second equation+learning =9. According to the previous settings, this equation can be expressed as: b+a=9. Now there are two equations: b = a 2 and b+a=9.
Substituting the first equation into the second equation gives: a 2+a = 9. This is a quadratic equation, and we can solve it by finding the root formula. By solving, we get: {a:-3+3i, b: 9+3i}, {a:-3-3i, b: 9-3i}, a=-3+3I, b=9+3I or a=-3-3I, and b=9-3I. But it should be noted that the sum and number in the title should be real numbers. So we can abandon the solution of imaginary part. Finally, we get: learning (a)=3, number (b)=9-3=6.
