What is the result of the division modeled by 46+(−23)+(−23)=46+2(−23)=0?(1 point)
The result of the division modeled by 46+(-23)+(-23) = 46+2(-23) = 0 is 0.
Imagine a family of farmers in the Neolithic Age. They are a multi-generational family living together on a large farm. They have bees, chickens, and other animals and crops that keep them fed. They have several shelters that are sturdy. Last year, however, floods came and took many of their large animals and rained out their crops. Some of the family died from starvation. They are replanting this year.
What cost and benefit of farming is shown in this situation?

Nomads might come to steal food or animals, but food surpluses lead to specialization of workers.

To solve this expression step-by-step, let's break it down:
Step 1: Simplify the expression in parentheses.
46 + (-23) + (-23) = 46 - 23 - 23
Step 2: Perform the addition and subtraction operations from left to right.
(46 - 23) - 23 = 23 - 23
= 0
So, the result of the expression is 0.
