right to left ٢ over ٥ space plus left parenthesis fraction numerator negative ٤ over denominator ٥ end fraction right parenth

= right to left fraction numerator ٢ space minus space ٤ over denominator ٥ end fraction equals negative ٢ ov

right to left negative ٣ over ٤ plus ١ ove

= right to left fraction numerator negative ٣ space plus space ١ over denominator ٤ end fraction equals fraction numerator negative ٢ over denominator ٤ end fraction equals negative ١

right to left fraction numerator negative ٤ over denominator ٩ end fraction plus left parenthesis fraction numerator negative ٧ over denominator ٩ end fraction right parenth

= right to left fraction numerator negative ٤ space minus ٧ over denominator ٤ end fraction equals fraction numerator negative ١١ over denominator ٤ end fraction equals negative ٣ o

right to left fraction numerator negative ٧ over denominator ١٠ end fraction minus ٩ ove

= right to left fraction numerator negative ٧ space minus ٩ over denominator ١٠ end fraction equals fraction numerator down diagonal strike negative ١٦ to the power of ٨ end strike over denominator down diagonal strike ١٠ subscript ٥ end strike end fraction equals negative

right to left ٣ over ٨ minus ٧ ove

= right to left fraction numerator ٣ space minus space ٧ over denominator ٨ end fraction equals fraction numerator negative ٤ over denominator ٨ end fraction equals negative ١

right to left negative ٥ over ٦ minus left parenthesis fraction numerator negative ٢ over denominator ٦ end fraction right parenth

= right to left fraction numerator negative ٥ space plus ٢ over denominator ٦ end fraction equals fraction numerator negative ٣ over denominator ٦ end fraction equals negative ١

right to left ٤ over ٩ ٥ space minus ٢ over

= (٥ - ٢) + (right to left ٤ over ٩ minus ٢ ove)

= ٣ + right to left ٢ over ٩ equals ٢ over

right to left negative ٣ over ٧ ١ plus left parenthesis negative ٢ over ٧ ٢ right paren

= {(-١) + (-٢)} {right to left left parenthesis fraction numerator negative ٣ over denominator ٧ end fraction right parenthesis plus left parenthesis fraction numerator negative ٢ over denominator ٧ end fraction right parenth}

= -٣ + (right to left fraction numerator negative ٥ over denominator ٧ end fracti) = right to left negative ٥ over ٧

right to left negative ٥ over ١�

= (٩ - ٣) + (right to left ١٦ over ١٦ minus ١٥ o)

= ٦ + right to left ١١ over ١٦ equals ١١ ov
