Mixed Operations

We will learn to calculate the combined operation, in the range of 1 000 000.

ADDITION & SUBTRACTION

EXAMPLE:

\(6\ 252 \,+ 13\,776\, -\, 25=\color{blue}{20\,003}\)

Step 1:
\(\begin{array}{rr} \small{\color{red}{1}}\space\,\small{\color{green}{1}}\space\space\,\,\small{\color{red}{1}}\quad\space\space\,\\6\,\space\space2\space5\space2 \\+\quad1\space3\,\space\space7\space7\space6 \\\hline2\space0\,\space\space0\space2\space8 \\\hline \end{array}\)

Step 2:
\(\begin{array}{rr} 2\space0\,\space\space0\space2\space8 \\-\quad\quad\quad\quad2\space5 \\\hline2\space0\,\space\space0\space0\space3 \\\hline \end{array}\)

MULTIPLICATION & DIVISION

EXAMPLE:

\(1\,008\times42\div7=\color{blue}{6\,048}\)

Step 1:
\(\begin{array}{rr} \small{\color{red}{3}}\space\space\space\, \\\small{\color{red}{1}}\space\space\space\, \\1\,\space\space0\space0\space8 \\\times\space\space\space\quad\quad\quad4\space2 \\\hline2\,\space\space0\space1\space6 \\+\quad4\space0\,\space\space3\space2\space\space\space \\\hline4\space2\,\space\space3\space3\space6 \\\hline \end{array}\)

Step 2:
\(\begin{aligned}\color{red}{6\,\space\space0\space4\space8} \\7\space\overline{)4\space2\,\space\space3\space3\space6} \\\underline{-\space4\space2}\quad\quad\,\space\space \\3\quad\space\space\\\underline{-\space0}\quad\space\space\\3\space3\space\space\space \\\underline{-\space2\space8}\space\space\space \\5\space6 \\\underline{-\space5\space6} \\0 \end{aligned}\)
