Add the following:
10 x 10
plus 2 x 10
plus 3 x 10
plus 2 x 3
That makes it easier to do it without a pen or calculator.
25
x>5
12 + 5 equals...
13/3 = 4 1/3 (To solve it you just divide 13/3, the answer is 4 but there is a remainder, so to solve for that remainder you just put it on top of the 3)
13*13=169. And its just memorization of squares. (i.e. 1*1=1,2*2=4, ...12*12=144, 13*13=169)
12 or 13 but its different for everybody
Factor out the GCF, which is p. p - 12 = 1 Solve for p. p = 13 Check it. (13 x 13) - (12 x 13) = 13 It checks.
Add 1 to each side : 15d = 13 Divide each side by 15: d = 13/15
wwe 13 is just like wwe 12 but u can do different things wwe 13 is basically a upgraded wwe 12
Neutrons. The number of protons is ALWAYS the same for the same element. Different forms of the same element, called isotopes, differ in the number of neutrons only and will react chemically in exactly the same way.
12 + x = 25remember you r trying to isolate the xstart by minusing 12 from both sidesx= 25-12so x=13
Certainly. Since you are born that way, some are undoubtedly 12-13 at the moment.
