Step-by-step explanation:
Given : expression (-5.12) - (-4.7) + (7.021)
We have to simplify the given expression.
Consider the given expression (-5.12) - (-4.7) + (7.021)
Apply plus - minus rule, [tex]\left(a\right)=a,\:-\left(-a\right)=a[/tex]
we have,
= - 5.12 + 4.7 + 7.021
Adding terms, we have,
= -5.12 + 11.721
Simplify , we get,
= 6.601
Thus, (-5.12) - (-4.7) + (7.021) = 6.601
