topic description

the first problem is to write a program to achieve 1 squared, 2 squared, 3 squared, and so on, up to the sum of squares of 10. Requirements: the square function is realized by the subroutine SQRT, and the program structure applies the loop structure.
the second problem is that ten signed numbers with absolute values less than 10 are stored in the internal RAM 60H to 69H respectively. Please modify the subroutine SQRT, in the first question above so that it can realize the signed multiplier, and calculate the sum of the ten signed multipliers, and store the sum in the internal RAM 6AH and 6BH.
