`[7-7times{(-64)-:((-4)timesbar(3-1))}+10]`

(7)/(3)times(1)/(4)=

[[(-8)times(-7)]-:[(-10)+(-4)]]

Show ((-8)/(7))times[(1)/(2)times((-4)/(3))]=[((-8)/(7))times(1)/(2)]times((-4)/(3))

((-4)/(3))times(1)/(2)+((-4)/(3))times((-7)/(5))

Show that (4)/(7)times((-2)/(8)+(3)/(4))=(4)/(7)times(-2)/(8)+(4)/(7)times(3)/(4)

((7)/(3))^(-3)times((9)/(4))^(0)times8^(-2)times((1)/(7))^(-1)

Evaluate: (-2) times (-3) times (-1) times (-4) times (-7)

The point of intersection of the lines bar(r)timesbar(a)=bar(b)timesbar(a) and bar(r)timesbar(b)=bar(a)timesbar(b) is 1. bar(a)-bar(b) 2. bar(a)+bar(b) 3. 2bar(a)+3bar(b) 4. 3bar(a)-2bar(b)
