Here is one of my questions that I solved with my maths mate.
4x54
I have decided to use the strategies place value and rounding and compensating.
Here is my strategy for rounding, and compensating.
4x54=216
+(4x6)=24
4x60=240
240-24(4x6)=216
This is my strategy for place value.
4x54=216
4x50=200
4x4=16
200+16=216
Hope you learned something from this.
Thank you ^_^
