[tex] \bf 25+ \underline{54:6}:3 \cdot10-49:7 \cdot4=[/tex]

[tex]\bf 25+ \underline{9:3} \cdot10-49:7 \cdot4=[/tex]

[tex]\bf 25+ \underline{3\cdot10}-49:7 \cdot4=[/tex]

[tex]\bf 25+30 - \underline{49:7 }\cdot4=[/tex]

[tex]\bf 25+30 - \underline{7 \cdot4}=[/tex]

[tex]\bf \underline{25+30} - 28=[/tex]
