Calculations in R

a <- (5 * 4)^(4 * 5) - 56
b <- 23 - 1 * (8 - 12)
c <- 56 / 8 * (3 + 4)
d <- 45 - 5 * 8 + (8 + 9)

a
## [1] 1.048576e+26
b
## [1] 27
c
## [1] 49
d
## [1] 22

Vectors a, b, and c

a <-    c(2,5,6,7)
b <-    c(1,0,9,8)
c <-    c(6,5,8,3)

a
## [1] 2 5 6 7
b
## [1] 1 0 9 8
c
## [1] 6 5 8 3
