a) \(\left|-6\right|-\left|-2\right|\)

b) \(\left|-5\right|.\left|-4\right|\)

c) \(\left|20\right|:\left|-5\right|\)

d) \(\left|247\right|+\left|-47\right|\)

Answer 1

a)

\(\left|-6\right|-\left|-2\right|=6-2=3\)

b)

\(\left|-5\right|\cdot\left|-4\right|=5\cdot4=20\)

c)

\(\left|20\right|:\left|-5\right|=20:5=4\)

d)

\(\left|247\right|+\left|-47\right|=294\)

Answer 2

a, \(\left|-6\right|-\left|-2\right|=6-2=4\)

b, \(\left|-5\right|.\left|-4\right|=5.4=20\)

c, \(\left|20\right|:\left|-5\right|=20:5=4\)

c, \(\left|247\right|+\left|-47\right|=247+47=294\)

Answer 3

a, \(\left|6\right|-\left|2\right|=6-2=4\)

b, \(\left|-5\right|.\left|-4\right|=5.4=20\)

c, \(\left|20\right|:\left|-5\right|=20:5=4\)

d, \(\left|247\right|+\left|-47\right|=247+47=294\)
