It is a square number because 20 times 20 = 400

As a product of its prime factors: 2*2*5 = 20 or as 22*5 = 20

23 - (Parenthesis, Exponents, Division, Multiplication, Addition, Subtraction) The answer would be 23. (do the multiplication first) 4 x 5. (20) then add the three. (20 plus 3 = 23)

It depends on whether the operation is addition, subtraction, multiplication, division, exponentiation or some other binary operation. One of the simplest answers is 20+20 and 10+30

You can reduce multiplication to repeated additions. You could also replace the resulting additions by repeated incrementing. For example, to calculate 20 + 13, continue counting 13 numbers from 20. But that would be extremely boring and inefficient. Better if you just learn to do it the way they teach in school.

4*5 + 6/3 = 20 + 2 = 22

Let's say the question was 4x5. The answer is 20. If a division question 20 divided by 5, you know its 4 from the multiplication question.

It doesn't PEMDAS The order of operations Parentheses Exponents Multiplication Division Addition Subtration So do what's in the parentheses first 8+12=20 6-1=5 Now do your division 20/5-4 The correct answer is 4

Division is multiplication of the inverse. The inverse of a being a^-1 or 1/a. For example, 20 divided by five is the same as 20 times 5^-1, or 20*(1/5)=4

It is a square number because 20 times 20 = 400

|20| and |-20|

As a product of its prime factors: 2*2*5 = 20 or as 22*5 = 20

1 x 20 2 x 10 4 x 5

Always remember that multiplication is the inverse/opposite of division, so they can be used to check each other. For example: Let's say the problem is 120 / 6. Whatever you think is your answer, you can multiple by 6 and that result should be 120. Is 120 / 6 = 10? No. The quick check is 10 * 6 = 60, which does not equal 120. Is 120 / 6 = 20? Yes! We know this is right because 20 * 6 = 120.

14=14 and 20=20 All numbers have different values, and the only number equal to itself is itself.
