Yes
20 . 2+0 = 2 20 divided by 2 makes 10. Is the same for 30,40,50,60,70,80 and 90.
2 x 20 = 40
2 times a number minus 17 plus 20 times a number minus 9 is the same as 2x - 17 + 20x - 9 = 22x - 26
Yes 2.0 is the same as 2 which is a whole number or an integer
To find which is bigger it is easier to convert both numbers to the same sort of fractions, so... 2/10 is the same as 4/20 1/4 is the same as 5/20 As you can see 1/4 is a bigger number than 2/10
20 . 2+0 = 2 20 divided by 2 makes 10. Is the same for 30,40,50,60,70,80 and 90.
Multiplication (of positive integers) can be defined as repeated addition. Thus, 2 x 23, for example, is the same as 23 + 23, while 3 x 20 = 20 + 20 + 20. Thus, adding a number to itself is equivalent to multiplying it by 2.Multiplication (of positive integers) can be defined as repeated addition. Thus, 2 x 23, for example, is the same as 23 + 23, while 3 x 20 = 20 + 20 + 20.

Is 2 the same as 20 - of anything?
2 x 20 = 40
2 times a number minus 17 plus 20 times a number minus 9 is the same as 2x - 17 + 20x - 9 = 22x - 26
16 = 2 x 2 x 2 x 2
60
Because subtracting a negative number is the same as adding a positive number. Subtracting -20 is the same as adding +20. 31 - (-20) = 31 + 20 = 51
Suppose the number is x. Then 7x = 2x + 20 Subtract 2x from both sides: 5x = 20 Divide both sides by 5: x = 4
Yes 2.0 is the same as 2 which is a whole number or an integer
The number of protons in an element does not depend on the charge of the element. An atom of a given element has the same number of protons as an isotope of that element. Thus, a calcium ion has 20 protons, just like atoms in calcium metal.
