Hi, I have had a few questions concerning the homework this week. MAB stands for MULTIBASE ARITHMETIC BLOCKS. They are the 10 base blocks and rods used in maths. Below is an image to explain how they work.
So if the question was: How many MAB minis in 3 tens and 21 ones, the answer would be 51. If the question was how many MAB minis in 7 tens and 35 ones, the answer would be 105.
