yes it is...21x4= 84
Oh, dude, 21 times 4 equals 84. It's like, basic math, man. Just multiply 20 by 4 which is 80, then add 1 times 4 which is 4, and boom, you got your answer. Math is cool, I guess.
21 21 because 21x4=84
The multiples of 21 up to 500 are as follows: 21x1=21 21x2=42 21x3=63 21x4=84 21x5=105 21x6=126 21x7=147 21x8=168 21x9=189 21x10=210 21x11=231 21x12=252 21x13=273 21x14=294 21x15=315 21x16=336 21x17=357 21x18=378 21x19=399 21x20=420 21x21=441 21x22=462 21x23=483 21x24=504
the four times table is incredibly easy! ill tell you them up to 26 1x4=4 2x4=8 3x4=12 4x4=16 5x4=20 6x4=24 7x4=28 8x4=32 9x4=36 10x4=40 11x4=44 12x4=48 13x4=52 14x4=56 15x4=60 16x4=64 17x4=68 18x4=72 19x4=76 20x4=80 21x4=84 22x4=88 23x4=92 24x4=96 25x4=100 26x4=104 i could go on and on. hope this helps!

Assuming the use of BODMAS, (5 x 2) + (21 x 4) = 10 + 84 = 94

A hand equals 4 inches, so 19 x 4 = 76". 76" divided by 12 = 6 foot 6 inches.
