Answer:

False.

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

  • |Absolute Value| - makes any number positive

Step-by-step explanation:

<u>Step 1: Define</u>

|18 - 7| = |18| + |-7|

<u>Step 2: Check</u>

  1. Subtract:                    |11| = |18| + |-7|
  2. Evaluate:                    11 = 18 + 7
  3. Add:                           11 ≠ 25

Here we see that 11 does <em>not</em> equal 25.

∴ The statement is false.
