Halfway. Brain filling. Great techniques but riddled with errors. others are page 50 - c is 216 page 51 - illustration 17 should be 18 page 52 - exercise c. what is 3,4? is this 3.4? answer is still wrong as it says 325 and should be 35 page 60-61 - 26x20 is 528 not 328 (incorrect 3 times) Enjoying this though!

Really liking this quick mental lessons so far. 'Cutting out numbers to solve addition' is so easy to do!
