Explain how you can use properties of operations as strategies to evaluate each expression using mental math. Then evaluate the expression.
a. 0.6+12.7+1.4+2.3
b. 4.5 + 3.9 + (−0.5) + (−4) c . 8 35 − 9 12 + 1 25
d. 485+678−385
I could use properties of operations as strategies to evaluate each expression using mental math by using PEMDAS, for example i could use distributive property in some decimals.
