Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$9.956-56$$

Answer

-46.044

Solution


Use this rule: \(a-b=-(b-a)\).
\[-(56-9.956)\]
Use the algorithm method.
4159910
56.000
-9.956
46.044
After simplification, we have:
\[-(56-9.956)=-46.044\]
Therefore, \(9.956-56=-46.044\).
\[-46.044\]
