Explanation:

Step1: Find number of 10th - grade students

Total students are 236 and 9th - grade students are 121. So, number of 10th - grade students is $236 - 121=115$.

Step2: Find number of right - handed 9th - grade students

There are 214 right - handed students and 103 of them are in 10th grade. So, right - handed 9th - grade students are $214 - 103 = 111$.

Step3: Find number of left - handed 9th - grade students

Number of 9th - grade students is 121 and right - handed 9th - grade students are 111. So, left - handed 9th - grade students are $121-111 = 10$.

Step4: Find number of left - handed 10th - grade students

Number of 10th - grade students is 115 and right - handed 10th - grade students are 103. So, left - handed 10th - grade students are $115 - 103=12$.

Step5: Find number of left - handed students

Left - handed 9th - grade students are 10 and left - handed 10th - grade students are 12. So, total left - handed students are $10 + 12=22$.
