B [2025 上海奉贤区期中] Do you know you can multiply (做乘法) by drawing just a few lines People started to use line multiplication (线性乘法) many centuries ago. It might help you when you don’t have a calculator (计算器)。 Work out the place values (位值) of your numbers.For example, you are calculating 34×12. The first number has a 4 in the ones place (个位) and a 3 in the tens place. Your second number has a 2 in the ones place and a 1 in the tens place. Draw parallel (平行) lines to represent (代表) your first number.Draw three lines to represent the tens place. Draw four lines above them to represent the ones place. Draw parallel lines to represent the second number.Draw one line to represent the tens place. The line should cross over the lines from the first number. Then, draw two lines below it to represent the ones place. Draw dots at each point where the lines meet each other. Circle the dots representing the ones place and add them up.Here, you will count eight dots. So the ones place of your answer will be 8. Circle the dots representing the tens place and add them up.You will count 10 dots here. Like any time you add or multiply, once a digit (数位) reaches 10, you need to carry (进位). In this example, you should put a 0 in the tens place and carry the 1 over to the hundreds place. Count the dots representing the hundreds place. Write down your answer. For 34×12, the answer is 408.
