|a| = -a for a < 0
|a| = a for a ≥ 0
examples:
|-1| = -(-1) = 1; |-4| = -(-4) = 4; |-0.1| = 0.1; |-109| = 109
|7| = 7; |19| = 19; |0| = 0
- |-7 + 4| = - |-3| = - (3) = -3
Answer: -|-7 + 4| = -3
Answer:
probably square root of 5
![\bf 10\cdot [2+(24-8)]\div 4\implies \stackrel{\mathbb{PEMDAS}}{10\cdot [2+(16)]\div 4}\implies 10\cdot [18]\div 4 \\\\\\ 180\div 4\implies 45](https://tex.z-dn.net/?f=%5Cbf%2010%5Ccdot%20%5B2%2B%2824-8%29%5D%5Cdiv%204%5Cimplies%20%5Cstackrel%7B%5Cmathbb%7BPEMDAS%7D%7D%7B10%5Ccdot%20%5B2%2B%2816%29%5D%5Cdiv%204%7D%5Cimplies%2010%5Ccdot%20%5B18%5D%5Cdiv%204%0A%5C%5C%5C%5C%5C%5C%0A180%5Cdiv%204%5Cimplies%2045)
