[tex]10^2\div5\cdot3+7=200[/tex]
For the calculation on the right to have the given result, you have to put the addition on parentheses:
[tex]\begin{gathered} 10^2\div5\cdot(3+7) \\ 100\div5\cdot10 \\ 20\cdot10 \\ 200 \end{gathered}[/tex]
*-*
Same as before, for this equation to be true, you have to put the addition between parentheses:
[tex]15\div5\cdot2+4=18[/tex][tex]\begin{gathered} 15\div5\cdot(2+4) \\ 3\cdot6 \\ 18 \end{gathered}[/tex]
