SALE❣️ Toshin High School Math B [Advanced] 3-book set Sequences Probability Distributions and Statistics Vectors Total of 3 textbooks These were given to my child at Toshin High School 3-4 years ago. I'm not sure if they didn't attend the classes or if they lost the textbooks, but there are no signs of use, and they appear to be brand new. The example problems all have answers, so even if you can't take Toshin's classes, you can still review broadly just by solving those☆ ■Writing As far as I can see, there are no signs of use, and there is no writing. They are probably brand new, but please understand if I missed anything. ■Condition/Other Product in near-new condition They have been stored at home, so please understand that there may be some scratches, folds, or minor stains on the exterior. No name written
