Answer 1

Explicație pas cu pas:

$25 + 54 \div 6 \div 3 \times 10 - 49 \div 7 \times 4 = \\ = 25 + 9 \div 3 \times 10 - 7 \times 4 = \\ = 25 + 3 \times 10 - 28 = \\ = 25 + 30 - 28 \\ = 55 - 28 = \\ = 27$

Answer 2

$\bf \red{ \underline{27}}$

Explicație pas cu pas:

$\bf 25+ \underline{54:6}:3 \cdot10-49:7 \cdot4=$

$\bf 25+ \underline{9:3} \cdot10-49:7 \cdot4=$

$\bf 25+ \underline{3\cdot10}-49:7 \cdot4=$

$\bf 25+30 - \underline{49:7 }\cdot4=$

$\bf 25+30 - \underline{7 \cdot4}=$

$\bf \underline{25+30} - 28=$

$\bf \underline{55- 28}= \red{ \underline{27}}$
