Evaluate \(5 + 4 \times 3\)
\(17\)
\begin{aligned}5+4 \times 3 &=5+12 \\&=17\end{aligned}
Evaluate \(7 \times 6 - 4 + 12 \div 2\)
\(44\)
\begin{aligned}7 \times 6-4+12 \div 2 &=42-4+6 \\&=38+6 \\&=44\end{aligned}
Evaluate \((7.15 - 4.5) + (2.4 + 1.6)\)
\(6.65\)
\begin{aligned}(7.15-4.5)+(2.4+1.6) &=2.65+4 \\&=6.65\end{aligned}
Remove brackets and simplify: \(3(x-7)\)
\(3x-21\)
\begin{aligned}3(x-7) &=3 \times x-3 \times 7 \\&=3 x-21\end{aligned}
Remove brackets and simplify: \(6(x-1)-4(x-2)\)
\(2x+2\)
\begin{aligned}6(x-1)-4(x-2) &=6 x-6-4 x+8 \\&=2 x+2\end{aligned}
