This is why multiplication is sometimes called 'times'.\nMore examples:\n7 x 3 = 7 + 7 + 7 = 21\n2 x 1 = 2\n3 x 6 = 3 + 3 + 3 + 3 + 3 + 3 = 18"

      "text": "There are a few different signs that people use to indicate multiplication. The most common is the 'x' sign, but sometimes people use a '*' sign or other symbols. Here are some ways to indicate 5 multiplied by 4.\n5 x 4\n5 * 4\n5 times 4\nSometimes when people use variables in multiplication they will just put the variables next to each other to indicate multiplication. Here are a few examples: \nab = a x b\n(a +1)(b + 1) = (a +1) x (b + 1)"
