​Reason about inequalities by:

• Using substitution to determine whether a given number in a specified set makes an inequality true.

• Writing an inequality of the form 𝑥 > 𝑐 or 𝑥 < 𝑐 to represent a constraint or condition in a real-world or mathematical problem.

• Recognizing that inequalities of the form 𝑥 > 𝑐 or 𝑥 < 𝑐 have infinitely many solutions.

Apply and extend previous understandings of addition and subtraction.

• Describe situations in which opposite quantities combine to make 0.

• Understand 𝑝+𝑞 as the number located a distance q from p, in the positive or negative direction depending on the sign of q. Show That a number and its additive inverse create a zero pair.

• Understand subtraction of integers as adding the additive inverse, 𝑝−𝑞=𝑝+(–𝑞). Show that the distance between two integers on the number line is the absolute value of their difference.

• Use models to add and subtract integers from -20 to 20 and describe real-world contexts using sums and differences.
