Reversibility
This week I've been learning about reversibility.
Reversibility is a way to make subtraction equations easier by just reversing the equations into an addition equation for example:
let's take 3267-1352 then let's reverse it
into
1352+ =3267 once you've reversed the equation then figure out what the equation is
Add up the numbers you got then voila you've got your answer
so your answer
1352+ =3267
+8
+40
+600
+1000 =1915 so
+200
+60
+7
So if you now know how to use reversibility then try to use it when you have a subtraction equation and it will make maths so much better.
