⑤ 37 * 5 = _____________
⑥ 27 * 6 = _____________
⑦ 332 * 6 = _____________
⑧ 2,958 * 7 = _____________

Explanation:

Step1: Calculate \(37\times5\)

We can use the distributive property: \(37\times5=(30 + 7)\times5 = 30\times5+7\times5=150 + 35 = 185\)

Step2: Calculate \(27\times6\)

Using the distributive property: \(27\times6=(20 + 7)\times6=20\times6 + 7\times6 = 120+42 = 162\)

Step3: Calculate \(332\times6\)

We break down \(332\) as \(300+30 + 2\), then \(332\times6=(300 + 30+2)\times6=300\times6+30\times6 + 2\times6=1800+180 + 12=1992\)

Step4: Calculate \(2958\times7\)

We can calculate it as \((2000 + 900+50 + 8)\times7=2000\times7+900\times7+50\times7 + 8\times7=14000+6300+350+56 = 20706\)

Answer:

\(37\times5 = 185\)
\(27\times6 = 162\)
\(332\times6 = 1992\)
\(2958\times7 = 20706\)
