joseph and yuka week 4 reflection

this week, we have a lot of fun and also do a lot of stuff. At maths, we learn about order of operations. Order of operations is like example: 100 + 25 - 5. Because the plus comes first, you add 100 + 25 first, and then you subtract it with 5. But if it's like this: 1 + 10 x 20, you times 10 and 20 first, but if it's like this:100 x (10 + 8), you add 10 and 8 first, that's what ms.Lenny told us.
