الحل
د) ( 40 × 5 ) × 7 = 200 × 7 = 1400
ه) ( 89 + 1 ) + 15 = 105
1) ( 7 × 3 ) + ( 7 × 4 ) = 49
2) ( 5 × 6 ) + ( 5 × 2 ) = 40
3) ( 3 ( 9 + 6 )) = 45
4) 4 ( 12 + 5 ) = 68 ريالاً
5) 44 + 39 = 83
6) 100 × 33 = 3300
7) ( 2 × 6 ) + ( 2 × 7 ) = 26
8) ( 5 × 8 ) + ( 5 × 9 ) = 85
9) 4 ( 3 + 8 ) = 44
10) 6 ( 200 + 7000 ) = 1200 + 42000 = 43200
11) = 5 ( 20 + 7 ) = 100 + 35 = 135
12) ( 91 + 9 ) + 15 = 115
13) ( 13 + 17 ) + 31 = 61
14) ( 85 + 15 ) + 46 = 146
15) ( 5 × 30 ) × 12 = 1800
16) ( 2 × 50 ) × 16 = 1600
17) ( 5 × 8 ) × 3 = 40 × 3 = 120
18) 7 ( 9 - 3 ) = 42
19) 12 ( 8 - 6 ) = 24
20) 6 ( 7 - 3 ) = 36
21) ص + 5
22) 6 جـ + 6
23) 5ف + 12
