Calculus I, II and III

To calculate the product of 70 and 4, you will need to perform a multiplication operation. Multiplication is one of the four elementary mathematical operations of arithmetic; with the others being addition, subtraction, and division. The multiplication of two whole numbers is equivalent to adding as many copies of one of them, the multiplicand, as the quantity of the other one, the multiplier. Both numbers can be referred to as factors. Here is how you would calculate the product step by step: Step 1: Set up the multiplication problem. You want to multiply 70 by 4, which can be written as \( 70 \times 4 \). Step 2: Multiply the numbers. You multiply the tens place in the first number by the second number since 70 is the same as \( 7 \times 10 \). \( 70 \times 4 = (7 \times 10) \times 4 \) Step 3: Apply the associative property of multiplication. The associative property states that you can change the grouping of the factors and it will not change the product. This means you can multiply 7 by 4 first and then multiply the result by 10. \( (7 \times 10) \times 4 = 7 \times (10 \times 4) \) Step 4: Multiply 7 by 4. \( 7 \times 4 = 28 \) Step 5: Multiply the result by 10. \( 28 \times 10 = 280 \) Therefore, the product of 70 and 4 is 280. In conclusion, \( 70 \times 4 = 280 \).
