Yohaku

Yohaku Junior puzzles are based on yohaku puzzles but are aimed at primary-aged students. The puzzles focus on additive and multiplicative thinking and will help students become more efficient with their recall of certain facts as well as allowing them to develop their problem-solving skills. Your task is to fill in the empty cells such that they give the sum or product shown in each row and column. Clues are given for each puzzle either by giving one of the numbers in the cells are by giving the set of numbers involved.
