4. Сравни.

Для сравнения выражений сначала нужно вычислить их значения, а затем поставить нужный знак ($<$, $>$ или $=$). **Левый верхний блок:** 1. $16 \cdot 2 = 32$; $32 < 50$ 2. $34 + 12 = 46$; $2 \cdot 21 = 42$; $46 > 42$ 3. $25 + 5 = 30$; $25 \cdot 3 = 75$; $30 < 75$ 4. $40 - 7 = 33$; $39 \cdot 2 = 78$; $33 < 78$ 5. $80 : 8 = 10$; $69 - 60 = 9$; $10 > 9$ 6. $30 \cdot 3 = 90$; $99 - 8 = 91$; $90 < 91$ 7. $70 + 2 = 72$; $71 + 9 = 80$; $72 < 80$ 8. $69 + 1 = 70$; $80 : 4 = 20$; $70 > 20$ 9. $90 - 6 = 84$; $84 < 818$ 10. $58 - 3 = 55$; $5 \cdot 11 = 55$; $55 = 55$ 11. $32 + 7 = 39$; $36 + 3 = 39$; $39 = 39$ **Правый верхний блок:** 1. $5 \cdot 20 = 100$; $100 < 1000$ 2. $48 - 4 = 44$; $50 : 5 = 10$; $44 > 10$ 3. $4 + 88 = 92$; $2 \cdot 24 = 48$; $92 > 48$ 4. $59 - 7 = 52$; $60 - 8 = 52$; $52 = 52$ 5. $190 > 98 + 2 (100)$ 6. $470 > 47 - 4 (43)$ 7. $36 \cdot 2 = 72$; $38 \cdot 2 = 76$; $72 < 76$ 8. $6 \cdot 9 = 54$; $3 \cdot 18 = 54$; $54 = 54$ 9. $10 \cdot 4 = 40$; $30 \cdot 2 = 60$; $40 < 60$ 10. $60 : 6 = 10$; $88 : 8 = 11$; $10 < 11$ 11. $7 \cdot 3 = 21$; $8 \cdot 2 = 16$; $21 > 16$ **Левый нижний блок:** 1. $68 : 2 = 34$; $38 - 2 = 36$; $34 < 36$ 2. $10 + 70 = 80$; $80 : 1 = 80$; $80 = 80$ 3. $33 \cdot 3 = 99$; $99 < 713$ 4. $54 - 44 = 10$; $84 : 21 = 4$; $10 > 4$ 5. $5 \cdot 11 = 55$; $6 \cdot 10 = 60$; $55 < 60$ 6. $21 : 3 = 7$; $48 : 6 = 8$; $7 < 8$ 7. $12 + 25 = 37$; $15 + 22 = 37$; $37 = 37$ 8. $36 - 7 = 29$; $48 - 12 = 36$; $29 < 36$ 9. $30 + 6 = 36$; $7 \cdot 5 = 35$; $36 > 35$ 10. $28 \cdot 2 = 56$; $18 \cdot 3 = 54$; $56 > 54$ 11. $60 : 4 = 15$; $70 : 5 = 14$; $15 > 14$ **Правый нижний блок:** 1. $45 - 1 = 44$; $48 - 4 = 44$; $44 = 44$ 2. $715 > 71 + 5 (76)$ 3. $10 \cdot 9 = 90$; $5 \cdot 4 = 20$; $90 > 20$ 4. $55 + 45 = 100$; $47 + 53 = 100$; $100 = 100$ 5. $64 : 2 = 32$; $30 + 3 = 33$; $32 < 33$ 6. $100 - 4 = 96$; $100 - 40 = 60$; $96 > 60$ 7. $6 \cdot 12 = 72$; $12 \cdot 6 = 72$; $72 = 72$ 8. $55 : 5 = 11$; $65 : 5 = 13$; $11 < 13$ 9. $20 \cdot 5 = 100$; $34 + 66 = 100$; $100 = 100$ 10. $98 - 8 = 90$; $89 - 3 = 86$; $90 > 86$ 11. $34 + 15 = 49$; $26 + 12 = 38$; $49 > 38$
