Maths Problem Solving-Week 3

WALT: Add and subtract decimals.



Start Writing Here: In Problem Solving I have been learning how to solve questions on my own. I have learnt that sometimes it is okay to solve questions with the simple solution. For example; 0.87-0.64=?. The simple way to work this out is by spiting them and then subtracting. It looks like this 0.8-0.6=0.2 and then we do 0.07-0.04=0.03. Once I have done this I will have the answer, 0.2+0.03=0.23. So the answer would be 0.23.
