Missing signs

(37 ------ 21) ------ 223 = 1000

(756 ------ 18) ------ 29 = 1218

27 ------ (36 ------ 18) = 675

31 ------ (87 ------ 19) = 2108

Each box represents a missing sign ( +, -, x, or ÷)

Missing signs

(37 -- x -- 21) -- + -- 223 = 1000

(756 -- ÷-- 18) – x -- 29 = 1218

27 -- + -- (36 – x -- 18) = 675

31 -- x -- (87 -- _ -- 19) = 2108

Each box represents a missing sign ( +, -, x, or ÷)

Alphabet soup

Alphabets A through R are printed above the box, in the box, and beneath the box. Can you continue on for S to Z and place them correctly according to the scheme ?

Above the box, the alphabets have only lines. In the box, they have lines and curves. Below the box, they have only curves.

Secret Code

Each letter stands for one of these digits – 1,3,4,6,8,9

A + A = B A x A = DFC + C = DB C x C= BDA + C = DE A x C= EF

Work out the following:E + F F + BE x F F x B

Secret Code

A cannot be 1 as there is no 2.

A cannot be 3 because A x A is a 2-digit number

A has to 4; B = 8

DF = 16; D = 1; F = 6

C + C = 18; C x C = BD = 81; C = 9

DE = 13; E = 3
