A unique puzzle game that combines problem-solving with pattern recognition
Left Overs is an engaging mathematical puzzle game where you answer questions to eliminate answers from a grid. Here's the twist: not all the values in the grid are answers to questions! Some are "left overs" - extra values placed as distractors. Your challenge is to answer all the questions correctly, identify which values remain, and calculate their total.
Specific to: Master Addition Calculations
Vertical or column addition of 2 or more digit values.
Click on a question from the question bank and calculate the answer. Use a whiteboard or paper to support your working as this isn't a mental mathematics task. If you are correct, the answer will be crossed off the answer grid. When all questions have been completed you will have some answers left. Add those into the given boxes, then add them together to find the final target number.
